Two coins are tossed simultaneously. Find the probability of getting at most 1 headat most 1 head.
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 at most one head.
Then, the favourable outcomes are HT, TH and TT.
Number of favourable outcomes = 3
∴ P (getting at most 1 head) = `"Number of favourable outcomes"/ "Total number of possible outcomes" = 3/4 `
