Question

In math class, the teacher asked students to randomly select a card and roll a number cube. There were 6 yellow cards, 4 blue, 8 red and 7 green cards. The number cube was numbered 1 through 6. What was the probability of choosing a green card and rolling an odd number?

Answer 1

7/50

Explanation:

Total number of cards: 6+4+8+7 = 25

Total number of numbers on the cube = 6

Number of green cards: 7

number of odd numbers on the cube: 3 [1,3,5]

Probability of getting a green card with a odd number :

`(7)/(25) * (3)/(6) \\\\(7)/(25) * (1)/(2)\\ \\(7)/(50)`
