Question

two coins are tossed together.find the probability of getting 1 at least one head 2 exactly one head 3 two heads​

Answer 1

1/2 is the probability of getting 1.

Answer 2

Step-by-step explanation:

If two coins are tossed then possible outcomes are: HH, HT, TH, TT

Total number of outcomes = 4

A. Number of favourable outcomes = 3

P(at least one heads) = Number of favourable outcomes/Total number of outcomes

= 3/4

B. Number of favourable outcomes = 2

P(one head) = 2/4

= 1/2

C. Number of favourable outcomes = 1

P(both heads) = Number of favourable outcomes/Total number of outcomes

= 1/4
