Question

Eight cards are picked three, four, five, six, seven, eight, nine, and 10 such that each card has exactly one of these numbers a card is picked without looking find each probability write each answer is a fraction and decimal and a percent P(9)

Answer 1

Probability (Fraction, Decimal, Percentage) = 1/8 , 0.125 , 12.5%

Explanation:

Total cards = 8 ; numbered 'three, four, five, six, seven, eight, nine, ten'

Prob (Card with number three) = card with no. three / total cards = 1/8

Prob (Card with number four) = card with no. four / total cards = 1/8

Similarly , Prob (A Card with any other number) = 1/8

Fraction Probability = 1/8 ; Decimal Probability = 0.125

Percentage probability = 1/8 x 100 = 12.5%
