Solution 1.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 4 appeared = 8

Probability

= No. of preferred outcomes/Total number of outcomes

= 8/80

= 1/10

= 0.1

Solution 2.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 2 appeared = 22

Probability

= No. of preferred outcomes/Total number of outcomes

= 22/80

= 11/40

= 0.275

2s to expect if dice is rolled 400 times

= 0.275 × 400

= 110
