Question

Harkeerat tosses 2 different coins simultaneously. Find the probability that she gets at least one head.

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

Let E be the event of getting at least one head

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

Favourable outcomes for at least one head is 3

P(E) = $\frac{\text{(Number of outcomes favourable to E)}}{\text{(Total number of outcomes)}}$ = $\frac{3}{4}$
