Answer:
j=1/2k+5/2
Step-by-step explanation:
2j−k=5
Step 1: Add k to both sides.
2j−k+k=5+k
2j=k+5
Step 2: Divide both sides by 2.
2j/2=k+5/2
j=1/2k+5/2

Probabilities are used to determine the chances of events
The probability that the salesman left his sunglasses in the first store is 0.16
<h3>How to calculate the probability</h3>
The given parameter is:
p = 1/5 ---- the probability that he left his sunglass
The probability that he did not leave his sunglass would be:
q= 1- 1/5
Evaluate the difference:
p = 4/5
So, the probability that the salesman left his sunglasses in the first store is:
Pr = 1/5 * 4/5
Evaluate the product
Pr = 4/25
Express as decimal
Pr = 0.16
Hence, the probability that the salesman left his sunglasses in the first store is 0.16
