What is probability of getting at most 1 head?
`3/4` Show Explanation: When two coins are tossed simultaneously, the possible outcomes are HH, HT, TH and TT. Total number of possible outcomes = 4 Let E be the event of getting at most one head. Then, the favourable outcomes are HT, TH and TT. Number of favourable outcomes = 3 ∴ P(getting at most 1head) = `("Number of favourable outcomes")/"Number of all possible outcomes" = 3/4` Age 11 to 14 |
