The probability that a new advertising campaign will increase sales is assessed as being 0.80?

The probability that the cost of developing the new ad campaign can be kept within the original budget allocation is 0.40. Assuming that the two events are independent, the probability that the cost is kept within budget and the campaign will increase sales is;

worked on this one a long time and I think it is 0.88, not 100% sure, thanks so much for looking at this problem.

    If they’re independent, 0.80 * 0.40 = 0.32.

    0.88??

    no, the answer is not .88, but .32. for independent events A and B with probabilities P(A) and P(B), the probability of both occurring is simply P(A)*P(B).
