Answer:
88 times
Step-by-step explanation:
The two comes up 20 out of 50 times
We don't know how many times 2 will come up if the die is rolled 220 times. We can, however, set up a proportion
20/50 = x/220 Cross multiply
50x = 20 * 220 Combine the right
50x = 4400 Divide by 50
50x/50 = 4400/50 Do the division
x = 88 times.
There might be typo error. The probability of any quantity is always less than or equal to 1. So, the probability is not possible. It should be .
Answer:
It means that the probability of getting a yellow or blue ball is 0.6.
Step-by-step explanation:
Given:
Y = set of yellow balls
B = set of blue balls
Therefore, the union of both the balls is given by the set Y U B.
The set Y U B represents the set that contains either yellow balls or blue balls but do not contain those balls that have both yellow and blue on them.
So,
Now, if , it means that the probability of getting a ball that has either yellow or blue on it is 0.6. In other words, if there are 100 balls, then the chances of getting a ball having either yellow or blue on it is 60%.
The answer to 45-15-15 is: D. 15.
Answer:
25.1
Step-by-step explanation:
Sin=opposite/hypotenuse
Sinx=4.2/9.9
x=arcsin(4.2/9.9)
x=25.1 degrees rounded from 25.102
0.007 < 0.07 < 0.69 < 0.7 < 0.701 < 0.71
