Answer:
The required probability is 0.1.
Step-by-step explanation:
red balls = 3
yellow balls = 2
blue balls = 5
Selected balls = 5
Number of elemnets in sample space = 10 C 5 = 1260
Ways to choose 1 red ball and 4 other colours = (3 C 1 ) x (7 C 4) = 105
Ways to choose 5 balls of other colours = 7 C 5 = 21
So, the probability is
Answer:
Step-by-step explanation:
<em><u>Given:</u></em>
<em><u>Solve for:</u></em>
<em><u>Solution:</u></em>
(1) Let's move all of components that do not contain (our target) to the right side (notice the change of sign of
from negative to positive):
(2) Let's divide both sides of equation by 4:
(3) Now, we simplify the left side:
This is the solution.
Hope this helps!
