Question

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?

• A. A
• B. C
• C. Both A and C
• D. None of these

Answer 1

Answer:

C. Both A and C

A = { ( H H H) } B = { (H H T) ( T H H ) ( H T H)} C = { (T T T)} D = {(H H H ) (H H T) ( H T H) (H T T)} An event is called simple if it has only one event So here A, C are simple events
