Question

A fair coin is tossed 8 times. Find the probability that it shows heads
exactly 5 times.​

Answer 1

Answer:

if the coin is tossed 8 times

then the sample space will be

S={H,H,H,H,H,H,H,H,T,T,T,T,T,T,T,T}

n(S)=16

event A will be

A=(H,H,H,H,H)

n(A)=5

therefore probability will be

p(A)=a(A)÷n(S)

=5÷16

therefore the probability is 5/16
