If four identical coins are tossed, (a) What is the probability of getting all four heads? plz ans​

Answer»

-step explanation:In counting the NUMBER of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get ANYONE of the FOLLOWING 4 OUTCOMES: HTTT, THTT, TTHT, or TTTH. Each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.
