A dice is rolled 50 times. The score for each throw is recorded in the table below.

Score-1 Frequency-11
Score-2 Frequency-5
Score-3 Frequency-7
Score-4 Frequency-9
Score-5 Frequency-12
Score-6 Frequency-

a) the relative frequency of scoring a 1 was calculated as 11/50 or 0.22
Work out the relative frequency, as a decimal, of throwing a 4.
b) how many times would you expect to roll a 5 when this dice is thrown 3000 times?
c) how many times would you expect to roll a 5 when a FAIR dice is thrown 3000 times?

PLEASE HELP!

 a) 0.18, b) 720, c) 500

Step-by-step explanation:

Since we have given that

Score-1 Frequency-11

Score-2 Frequency-5

Score-3 Frequency-7

Score-4 Frequency-9

Score-5 Frequency-12

Score-6 Frequency-50-(11+5+7+9+12)=6

a) relative frequency of scoring a 4 would be :

b) how many times would you expect to roll a 5 when this dice is thrown 3000 times?

It would become:

c) how many times would you expect to roll a 5 when a FAIR dice is thrown 3000 times?

It would become

As we know that probability of getting a 5 from the fair die is given by:

Hence, a) 0.18, b) 720, c) 500
