Answer :
1/4 for red
1/4 for blue
2/4 ( 1/2) for green
1/4 * 1/4 * 1/2 = 1/32
the denominator is the bottom number so it is 32
Answer: [tex]\frac{1}{32}[/tex]
Step-by-step explanation:
Given: Heather has a bag containing 4 marbles: 1 red, 1 blue, and 2 green.
She draws 1 marble out of the bag, replaces it, and then draws another marble, it means all the three events are independent.
Also we know that probability of any event = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]
therefore, the probability of drawing a red then blue then green marble is given by :-
[tex]\text{ P(red then blue then green)}=\frac{1}{4}\times\frac{1}{4}\times\frac{2}{4}\\\\\Rightarrow\ \text{ P(red then blue then green)}=\frac{1}{32}[/tex]
