I think the probability that Gwen will reach in her book bag purple eraser is 5/20 or 1/4
Answer:
1 / 5
Step-by-step explanation:
Given that:
Number of white marbles = 5
Number of blue marbles = 3
Number of green marbles = 7
Required is the approximate probability of drawing 2 green marbles, Note that drawing is done without replacement :
Probability = required outcome / Total possible outcomes
Total possible outcomes = sum of all marbles = (5 + 3 + 7) = 15 marbles
First draw:
P(Green) = 7 / 15
Second draw:
Required outcome = 7 - 1 = 6
Possible outcomes = 15 - 1 = 14
P(green) = 6 / 14
Probability of drawing out two green marbles :
(7/15 * 6/14) = 42 / 210 = 1 / 5
1 because he HAD 5 and if he gave his friend 4 than he has 1 left, 5-4=1 my friend.
When you take the absolute value of this equation, the answer should actually be 3.
You should solve the what’s inside first. If the answer is negative, then the absolute value will make it positive.
For example
|1-5|=|-4|=4
