Three coins are tossed, what is the probability that
theoutcome will be heads?

The probability that the outcome will be heads = 1/2

Step-by-step explanation:

Sample of Total outcome: HHH THH HHT HTT THH TTH TTH TTT

Possible outcome of heads = more than one head = HHH THH HHT THH

Where H = head, T = tail.

Probability = n(possible outcome)/n(total outcome)

n(possible outcome) = 4

n( total outcome) = 8

Therefore,

Probability = 4/8.

Probability = 1/2

Thus The probability that the outcome will be heads = 1/2
