Kamila has two number cubes each labeled 1 to 6. she is going to conduct an experiment by tossing both cubes a total of 150 times. she will find the sum of the two numbers in each role a. possible outcomes? b. probability of tossing a sum of six? c. how many times should kamila toss a sum of 7? d. how many times should kamila toss a sum of 10 or greater?

Step-by-step explanation:

a) When two number cubes are thrown possible outcomes are

b) Probability of tossing a sum of 6

Favourable outcomes = (1,5)(5,1)(2,4) (4,2) (3,3)  

Hence probability =

c) For getting 7 favourable outcomes are

(1,6)(2,5)(3,4)(4,3)(5,2)(6,1)

i.e one out of 6 chances.

Hence in 150 times Kamala should toss a sum of 7 ---  

d) Favourable outcomes for sum of 10 or greater

= (4,6) (6,4) (5,5) (5,6)(6,5)(6,6)

Probability for getting sum of 10 or greater =

No of times Kamila should toss 10 or greater

=
