Which sentence?
when you give the sentence,I will answer☼
The correct answer for the question that is being presented above is this one: the experimental probability that Dree will roll a strike in the first frame of the next <span>game</span>
prob = 6/10 = 3/5
a cube has 6 sides, so division by 6 would be the model for probs, we need a division by 5 or 10 or 15 ,etc
Correct answer is: P(x<6) is 0.123 and it is usual.
Solution:-
Given that the time a person takes to decide which shoes to purchase follows normal distribution. Which has mean = 8.21 minutes and standard deviation 1.90
Then probability of individual takes less than 6 minutes is
P(X<6) = ![P(z](https://tex.z-dn.net/?f=P%28z%3C%5Cfrac%7Bx-mean%7D%7Bstandard%20deviation%7D%20%29)
= ![P(z](https://tex.z-dn.net/?f=P%28z%3C%5Cfrac%7B6-8.21%7D%7B1.90%7D%20%29%3DP%28z%3C-1.163%29)
= 0.1230
Typically we say an event with a probability less than 5% is unusual.
But here P(X<6) = 0.123 is greater than 5% hence this is usual.
