Alot of 100 semiconductor chips contains 20 that are defective. (a) two are selected, at random, without replacement, from the lot. determine the probability that the second chip selected is defective. (b) three are selected, at random, without replacement, from the lot. determine the probability that all are defective.

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
