उत्तर
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`.
