Question

A bag with 8 marbles has 4 yellow marbles, 3 blue marbles, and 1 red marbles. What is the probabillity that it chosen at random and is yellow?

Answer 1

• Total marbles=8
• Yellow marbles=4

Probability of yellow:-

P(Y):-

• 4/8
• 1/2
• 0.5

Answer 2

1/2 = 0.5 = 50%

Explanation:

Given:

• Yellow marbles = 4
• Blue marbles = 3
• Red marbles = 1
• Total marbles = 8

`\sf Probability\:of\:an\:event\:occurring = (Number\:of\:ways\:it\:can\:occur)/(Total\:number\:of\:possible\:outcomes)`

`\implies \sf P(yellow) = (4)/(8)=\frac12`

This can also be written as 0.5 or 50%
