Question

from a bag of marbles, 4 of the marbles picked out were red. 6 of the marbles picked out were blue. what is the experimental probability that the next marble drawn will be red? write your answer as a fraction. p(red)= _

Explanation:

Step1: Find total number of marbles picked

Total marbles = 4 (red) + 6 (blue) = 10

Step2: Calculate experimental - probability of red

Experimental probability of red = $\frac{\text{Number of red marbles}}{\text{Total number of marbles picked}}$ = $\frac{4}{10}$ = $\frac{2}{5}$

Answer:

$\frac{2}{5}$
