Question 932961:  A die has faces that are numbered: 1, 1, 2, 2, 3, 6 
(i) A game consists of throwing the die two times. 
1. Draw a table to list the outcomes when the die is rolled twice the 
two scores added to give a total score. 
2. Calculate the probability that the total score on the two dice is: 
I. 7, 
II. greater than 5, 
III. an even number, 
 IV. less than 4, 
 V. a multiple of 3. 
(ii) Paul rolls a die 300 times. Using a Binomial model, 
1. determine how many sixes would you expect him to obtain. 
2. find the probability that he obtained 55 sixes.

You can  put this solution on YOUR website! __1_1_2_2_3_6 
1|_2_2_3_3_4_7 
1|_2_2_3_3_4_7 
2|_3_3_4_4_5_8 
2|_3_3_4_4_5_8 
3|_4_4_5_5_6_9 
6|_7_7_8_8_9_12
 
.....count them 
P(sum = 7) = 4/36 = 1/9 
P(sum > 5) = 12/36 = 1/3 
P(sum < 4) 
P(sum = a multiple of 3) 
........ 
Paul rolls a die 300 times. 
p(6) = 1/6 
Exp 6s = (1/6)300 = 50 
P(x = 55) = binompdf(300, 1/6, 55) = .0444 0r 4.44%
