if three unbiased coins are to see what is the probability of getting,1 head,2 head,atlist 2head, at most 1 head

Answer 2

Step-by-step explanation:

A-probability of getting 1 head

n(s)=8

n(A)=3

p(A)=n(A)/n(s)

=3/8

B-probability of getting 2 heads

n(B)=3

p(B)=n(B)/n(s)

3/8

C-probability of getting atleast 2 head

n(C)=4

p(C)=n(C)/n(s)

=4/8=1/2

D-probability of getting atmost one head

n(D)=4

p(D)=n(D)/n(s)

= 4/8=1/2
