Question

Two coins are tossed simultaneously. The probability of getting at the most one head is ______.

Options

• `1/2`

• `1/4`

• `3/4`

• 1

Answer 1

Two coins are tossed simultaneously. The probability of getting at the most one head is `bbunderline(3/4)`.

Explanation:

When two coins are tossed simultaneously

Sample Space = {HH, HT, TH, TT}

Thus, 

Probability of getting at most one head = `({T T, HT, TH})/({HH, HT, TH, T T})`

= `3/4`

Thus, the probability of getting at most one head is `3/4`.
