The probability of getting two heads when two fair coins are tossed to

1.	The probability of getting two heads when two fair coins are tossed together is :(a) 1/3(b) 1/4(c) 1/2(d) 1
Answer» Correct answer is (b) 1/4 When two coins are tossed the number of outcomes = 4 {HH, TT, HT, TH} The favorable outcomes = 1 {HH} ∴ Probability of getting two head \(=\frac{\text{Favourable outcomes}}{\text{Total no. of outcomes}}\) \(=\frac{1}{4}\)

Answer»

Correct answer is (b) 1/4

When two coins are tossed the number of outcomes = 4 {HH, TT, HT, TH}

The favorable outcomes = 1 {HH}

∴ Probability of getting two head

\(=\frac{\text{Favourable outcomes}}{\text{Total no. of outcomes}}\)

\(=\frac{1}{4}\)
