Answer:
5/36
Step-by-step explanation:
There are 5 sums that will give you 8:
2+6, 3+5, 4+4, 5+3, 6+2
There are 36 possible outcomes from rolling 2 dice, so your probability of rolling 8 is ...
5/36
Answer: 2.5%
Step-by-step explanation:
Mean score = 65
Standard deviation = 5
Score (x) = >75
Z-score = [(score - mean) ÷ standard deviation]
Z - score = [(75 - 65) ÷ 5]
Z - score = 10 ÷ 5 = 2
P(score higher than 75) = 100 - 95 = 5/2 = 2.5%
15 because in the table 10=12.50 so to find how much 1 is you have to move the decimal one place to the left (1.25). Then you have to do 1.25x12 which gives you 15. Hope this helps!
