Question

Bellman, Bonnet-Maker, Barrister, Broker, Billard-Marker, Banker, Butcher, Baker, and Beaver are going snark hunting. The average number of snarks they spot is 3.5 per day. Find the probabilities of...

a)...spotting exactly 5 snarks tomorrow

b) ...spotting at least 2 snarks tomorrow

c)...spotting exactly 23 snarks in the coming week

4)...spotting exactly 4 snarks tomorrow and exactly 3 snarks the next day

Answer 1

Let X denote number of snakes spot in a day here,

1. Probability of spotting exactly 5 snakes tomorrow = P(s = 5) = 0.1221
2. Probability of spotting at last 2 snaker tomorrow = P = 0.3208
3. Probability of spotting 23 snaker in coming week

Ler x1, x2 ….x4 be days in a week we have to find

1. Probability of spotting exactly 4 snaker tomorrow and exactly 3 snake the next day.

Let X1 be no of snaker spoting tomorrow and x2 be no of snaker spotting on next day

We have to find

Let X1 be no of snaker spoting tomorrow and x2 be
