Question

Two unbiased coins are tossed simultaneously. Find the probability of getting no heads.

• A.
• B. 0
• C.
• D.

Answer 1

The correct option is A

Let us write down the outcomes when 2 coins are tossed together - Heads (H) and Tails (T): HH, HT, TH, TT

Favourable outcomes for no heads is 1

P(E) = $\frac{\text{(Number of outcomes favourable to E)}}{\text{(Total number of outcomes)}}$ = $\frac{1}{4}$
