Question

The probability of selecting a red ball at random from a jar that contains only red, blue and

orange balls is 14 . The probability of selecting a blue ball at random from the same jar is 13 . If

the jar contains 10 orange balls, find the total number of balls in the jar​

Answer 1

Answer:

24

Step-by-step explanation:

let the total number of balls in jar be x

then number of blue ball in jar = 1/3×x = x/3

and number of red balls = 1/4×x = x/4

and number of orange balls = 10

x = x/3 + x/4 + 10

= 12x = 3x + 4x + 120

= 12 - 7x = 120

= 5x = 120

= x = 24

therefore the total number of balls in the Jar is 24
