Answer: The required probability is 0.82.
Step-by-step explanation:
Since we have given that
Number of projects = 3
So, probability of getting each project = 
Probability of first path being completed in 43 days = 0.7
Probability of second path being completed in 43 days = 0.85
Probability of third path being completed in 43 days = 0.90
So, Probability that the project will be completed on time would be

Hence, the required probability is 0.82.

Step-by-step explanation:
Question 3
5 (k + 4) - 2k
Use distributive property of multiplication.
5k + 20 -2k
Combine like terms to get your answer.
3k +20
Question 4
2 (3 + d - 1)
Simplify the expression in the parenthesis.
2 (2 + d)
Use distributive property of multiplication.
4 + 2d
If you wanted it to be accepted at higher levels, switch the terms around.
2d + 4
