Answer:
a)

b) 0.476
c) 0.667
Step-by-step explanation:
We are given the following in the question:
Y = the number of forms required of the next applicant.
Y: 1, 2, 3, 4, 5, 6
The probability is given by:

a) Property of discrete probability distribution:

b) at most four forms are required

c) probability that between two and five forms (inclusive) are required

There will be 100 hand shakes because you would do 10x10 which is 100
The answer is= there are 126 5p coins
the reason for this is that
-630 is simplified to 5,
-so 1/5 is really 126/630,
(630 divided by 5 is 126)
- and so 2/5 is 126 x 2 =252/630
- there are only 3 parts left, and if 1p has more parts than 5p,
-then 1p takes up 2/5 of the bag
-and 5p takes up 1/5 of the bag
