One card is drawn from a well shuffled deck of 52 cards. If each outcome is equally likely, calculate the probability that the card will be a diamond
Three coins are tossed once. Let A denote the event “three heads show”, B denote the event “two heads and one tail show”. C denote the event “three tails show” and D denote the event ‘a head shows on the first coin”. Which events are compound?
Three coins are tossed once. Let A denote the event “three heads show”, B denote the event “two heads and one tail show”. C denote the event “three tails show” and D denote the event ‘a head shows on the first coin”. Which events are simple?
Three coins are tossed once. Let A denote the event “three heads show”, B denote the event “two heads and one tail show”. C denote the event “three tails show” and D denote the event ‘a head shows on the first coin”. Which events are mutually exclusive?
Two dice are thrown and the sum of the numbers which come up on the dice is noted. Let us consider the following events associated with this experiment
A: ‘the sum is even’.
B: ‘the sum is a multiple of 3’.
C: ‘the sum is less than 4’.
D: ‘the sum is greater than 11’.
Which pairs of these events are mutually exclusive?
If E_{1} , E2, E3,......... En are n events of a sample space S & if E UE 2 I E 3 ..........U E_{n} = S then events E_{1}, E_{2}, E_{3} ,......,E n are called
Consider the experiment of rolling a die. Let A be the event ‘getting prime number’, B be the event ‘getting an odd number’. Write the set representing the event A but not B
Consider the experiment of rolling a die. Let A be the event ‘getting prime number’, B be the event ‘getting an odd number’. Write the set representing the event ‘not A’.
Consider the experiment of rolling a die. Let A be the event ‘getting prime number’, B be the event ‘getting an odd number’. Write the set representing the event A and B
Consider the experiment of rolling a die. Let A be the event ‘getting prime number’, B be the event ‘getting an odd number’. Write the set representing the event A or B
If S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}
and A={HTH, HHT, THH} then {HHH, HTT, THT, TTH, TTT} is called :
An experiment is called random experiment if it satisfies
- It has more than one possible outcome.
- It is not possible to predict the outcome in advance
When a coin is tossed it may turn up a head or a tail but we are not sure which one of these results will actually be obtained. Such experiment are called __________
A jar contains 24 marbles, some are green and others are blue. If a marble is drawn at random from the jar, the probability that it is green is 2/3. Find the number of blue balls in the jar?
A bag contains 5 red balls and some blue balls. If the probability of drawing a blue ball is double that of a red ball. Determine the number of blue balls in the bag?

There are 50 mangoes in a basket, 20 of which are unripe. Another basket contains 40 mangoes, with 15 unripe. If we take one mango from each basket, what is the probability of both being unripe?
