Question

Two coins are tossed together, find the probability of getting :
(i) Exactly two heads (ii) Atleast one tail (iii) Atmost one tail (iv) No tails

Answer 1

Answer:

No. of coins = 2

(i) Exactly two heads

Probability of getting 2 heads = Total outcomes/ No. of outcomes

= 2/2 = 1

So probability is = 1

Answer 2

Answer:

i)A=(The probability of getting 2 heads)

A={ ( h,h)}

ii)B=( the probability of getting atleast one tail)

B={(h,t),(t,h)}

iii)C=(the probability of almost one tail)

C={( h,t), ( t,h),(t,t)}

iv)D=( the probability of getting no tail)

D={(h,h)}
