प्रश्न
Two coins are tossed simultaneously. Find the probability of getting exactly 1 head.
उत्तर
When two coins are tossed simultaneously, all possible outcomes are HH, HT, TH and TT.
Total number of possible outcomes = 4
Let E be the event of getting exactly one head.
Then, the favourable outcomes are HT and TH.
Number of favourable outcomes = 2∴ P(getting exactly 1 head) = `"Number of favourable outcomes"/"total number of posible outcomes" = 2/4 = 1/2`
