Question

Two coins tossed. Find the probability of getting:
a) one head
b) exactly 2 tall
c) atleast one head​

Answer 1

Step-by-step explanation:

s=(tt th ht hh)

n(s)=4

a=(th ht)

n(a)=2

p(a)=n(a)/n(s)

p(a)=2/4

p(a)=1/2

b=(tt)

n(b)=1

p(b)=n(b)/n(s)

p(b)=1/4

c=(th ht hh)

n(c)=3

p(c)=n(c)/n(s)

p(c)=3/4
