Answer:
a/b= 2/15
Explanation:
3a +b
----------- = 7/5
b
<h2>now cross multiple both side</h2>
5(3a+b)=7 x b
15a +5b = 7b
15a = 7b-5b
15a = 2b
15a/2b = 1
a/b x 15/2 =1
<h3>multiple both side
by 2/15</h3>
we get,
a/b = 2/15
hope you have no doubt now !
<h2>we get ,</h2>
Answer:
PART A
- Red: 7/29
- Blue: 8/29
- Yellow: 5/29
- Green: 9/29
PART B
- Red or blue: 7/29 + 8/29 = 15/29
- Yellow or green: 5/29 + 9/29 = 14/29
- Blue or yellow or green: 8/29 + 5/29 + 9/29 = 22/29
Explanation:
In this case where the question is asking or <u>OR</u> and the events are <u>mutually exclusive</u> (Mutually exclusive meaning you can't attain two or three different colors in one pick), the compound probability is the sum of the probability of each component event (Probability of Red <u>OR</u> Blue = P(Red) + P(Blue) = 7/29 + 8/29 = 15/29)
