This is a problem on a venn diagram in which the problem determines the number of subscribers that are mutually heeding for channel A and channel B. The equation to be followed is

U = U' + A + B + AandB
Substituting,
8500 = 5140 + 2450+1980- AandB
AandB = 1070 subscribers

topjm [15]

Answer: Our required probability is 0.55.

Step-by-step explanation:

Since we have given that

Probability that chance of winning the hotel bid = 40%

Probability that no chance of winning the hotel bid = 100-40=60%

Probability that chance of winning the office building bid = 25%

Probability that no chance of winning the office building bid = 100-25 = 75%

So, Probability that the company will win at least one contract is given by

$0.4\times 0.75+0.6\times 0.25+0.4\times 0.25\\\\=0.55$

Hence, our required probability is 0.55.
