You multiply the probability by 100.

pr(exactly 4 out of 8 cured) = ₈C₄ × (98/100)⁴ × (1 - 98/100)⁴ = 103305233920/10000000000000000 ≈ 0.00001

It can be, if desired. Probability is a number between 0 and 1. If you want to express that as a percent, simply say between 0% and 100% instead.

probability of 75 percent = 3/4

No. Probability is defined as a number between 0 and 1 (100 percent). If you have four oil wells, each with a probability of hitting being 30%, then the probability of at least one hitting is 100% - (100% - 30%)4, or about 76%.

The probability the shooter makes both shots is .7 * .7 = .49, and the probability of making neither is .3 * .3 = .09. So the probability of making exactly 1 out of 2 is 1 - .49 - .9 = .42, or 42 percent.

The probability is 0.68
