Question

Ritu has 3 shirts in shades of red, 4 in yellow shades and 5 in green shades. Three shirts are picked at random. The probability that all of these are in red shades is (a) (1/12) (b) (1/220) (c) (1/66) (d) (1/4)

Answer 1

Answer:

option (d) 1 / 4

Step-by-step explanation:

number of red colored shirts=3

number of yellow colored shirts=4

number of green colored shirts=5

total number of shirts=(3+4+5)=12

required probability=number of red colored shirts / total number of shirts

                                = 3 / 12 = 1 / 4

option d is the right answer
