In a survey of companies, it was found that 45 were in the mining sector, 72 were in the financial sector, 32 were in the IT sector and 101 were in the production sector,​

0.288

0.308

Explanation:

Given :

Mining sector = 45

Financial sector = 72

IT sector = 32

Production sector = 101

Total number of companies :

(45 + 72 + 32 + 101) = 250

A.)

Probability that a randomly selected company is in the financial sector

Recall :

Probability = required outcome / Total possible outcomes

P(company = financial) = (number of companies in financial sector / total number of companies)

P(company = financial) = 72 / 250 = 0.288

B.)

Company is either a mining or IT company :

P(company = Mining or IT) = (number of mining + number of IT Companies) / total number of companies

P(company = Mining or IT) = (45 + 32) / 250 = 77 / 250 = 0.308
