पर्याय

• `1/2`

• `3/4`

• `1/4`

• `3/8`

Answer 1

Two fair coins are tossed together. The probability of getting 2 heads is `bbunderline(1/4)`.

Explanation:

Where two fair coins are tossed together, the possibility is as follows:

{HH, HT, TH, TT}

∴ Total number of possible outcomes = 4

The possibility of getting 2 heads is 1, i.e. {HH}

∴ Number of favourable outcomes = 1

Thus, the probability of getting 2 heads = `("Number of favourable outcomes")/("Total number of possible outcomes")`

= `1/4`

Hence, the required probability is `1/4`.
