A tech dispersion store sells 64-megapixel and 128-megapixel cameras. This store got a shipment of 15 of these cameras, of which three have a goal of 64 megapixels. Assume that 5 of these cameras are picked to be put on the counter, the others are set in the basement. Leave X alone the quantity of 64 megapixel cameras, among the five picked to store them on the counter. The likelihood that X = 2 is:

a) 0.021978

b) 0.978021

c) 0.780219

d) 0.219780

Johnson Chemicals is thinking about two alternatives for its provider portfolio. Alternative 1 uses two nearby providers. Each has a "novel occasion" hazard of 4.5%, and the likelihood of a "super-occasion" that would handicap both simultaneously is assessed to be

1.3%. Choice 2 uses two providers situated in various nations. Each has a "extraordinary occasion" hazard of 14%,

'4

furthermore, the likelihood of a "super-occasion" that would cripple both simultaneously is assessed to be 0.18%.
