A geological study indicates that an exploratory oil well drilled in a certain region should strike oil with probability 0.1. Assume that striking oil (viewed as success) at one drilling location is independent of success at another location.

(a) Let X be the number of successful strikes if 8 wells are dug. What is the distribution of X.

(b) What is the probability of obtaining at least (inclusive) 3 oil strikes if 8 wells are dug?

(c) If 40 wells are drilled, what is the approximate probability that 8 or fewer will strike oil? Justify your choice of the approximating distribution by verifying the relevant condition(s).

Gexpressions: practice question 3 of 5 jackson wants to study the popularity of his music video by tracking the number of views the video gets on his website. the expression below represents the total number of views that jackson's video receives n days after he begins tracking the nu views, where b is the rate at which the number of views changes. alb)" select the statement that would accurately describe the effect of tripling a, the initial number of views before jackson beginst the rate at which the number of views changes, b, will triple. the total number of views the video has after n days, a(b)", will not change. the total number of days since jackson begins tracking views, n, will be reduced by one-third. the total number of views the video has after n days, alb)", will triple. submit
