Question

Three coins are tossed together. Find the probability of getting at most one tail.

Answer 1

Answer:

3/6

Step-by-step explanation:

first count all the faces of the cons that will be 6 then divide it by the number of tail that is 3 so 3/6 that is the probability of getting a tail

Answer 2

When three coins are tossed simultaneously

The total possible outcomes are ( H,H, H) , ( H,H,T), (H,T,H) , (T,H,H), ( T,H,T), (T,T,H), ( T,T,T)

The total number of outcomes is 8

For at most one tail, no. of tails should be either 0 or 1.

The favourable outcomes are (H,H,H), (H,H,T), ( H,T,H), (T,H,H)

No. of favourable outcomes = 4

Therefore, probability of occurrence of almost 1 tail = 4/8 = 1/2.
