Gin hire-assistant, assuming that the candidates are presented in a random order, what is the probability that you hire exactly one time? what is the probability that you hire exactly n times?

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

You can find it by multiplying the areas it show u
