Answer:
<em>15/16</em>
Explanation:
Probability: this can be defined as the ratio of the number possible outcome to number of total outcome of an event.
P(at-least one head and one tail) = n(possible outcome)/n(total outcome)................. Equation 1
Where P = probability. n = number H = head, T = tail
If the child flips the coin five times then,
sample of total outcome = HHHHH, THHHH, THHHH, TTHHH, THHHH, TTHHH, TTHHH, TTTHH, THHHH, TTHHH, TTHHH, TTTHH, TTHHH, TTTHH, TTTHH, TTTTH, THHHH, TTHHH, TTHHH, TTTHH, TTHHH, TTTHH, TTTHH, TTTTH, TTHHH, TTTHH, TTTHH, TTTTH, TTTHH, TTTTH, TTTTH, TTTTT
n( possible outcome) = 30
n(total outcome) = 32
P(at-least one head and one tail) = 30/32
P(at-least one head and one tail) = 15/16.
Hence the probability that she will receive at-least one head and one tail = 15/16
