Answer:
a = 12.93
Step-by-step explanation:
Convert to decimal: 12 1/3 = 12.3
Pythagoras (a^2 = b^2 + c^2):
4^2 = 16
12.3^2 = 151.29
16+151.29 = 167.29
a = √167.29
a = 12.93 (rounded to two decimal places)
Answer:
Step-by-step explanation:
Given that, we have a number cube label 1,2,3,4,5 and 6.
Then, the sample space is
S= {1, 2, 3, 4, 5, 6}
The probability of rolling a number different from 9?
Since we don't have 9 in the sample space, then the probability of rolling a number different from 9 will be the have 1,2,3,4,5 and 6 as the outcome
Then,
Pr(rolling number different from 9) = 6 / 6 = 1
Pr(rolling number different from 9) = 1.
The second option is correct.
