Hmm I think the answer is 95%
1 standard deviation is 13
To find out the range of scores that fit 1 standard deviation from the mean, you would have to take away and add 13 from the mean (133) this gives a range of 120-146 which isn’t right because you’re looking for 107-159.
Next, look for 2 standard deviations from the mean which is just 13 x 2=26.
To find the range of scores that are 2 standard deviations from the mean take away and add 26 to the mean (133) which gives a range of 107-159. This is the correct answer.
2 standard deviations represents 95% of the data. That’s why I think the answer is 95%.

<u>Answer:</u>
Two events, A and B, are independent. If P(A) = 0.3 and P(B) = 0.2.The value of P(A and B) is 0.06
<u>Solution:</u>
Given that P(A) and P(B) are two independent events which means the occurrence of one event does not affect the occurrence of another event.
Here we have to find out P(A and B)
When P(A) and P(B) are two independent events, then P(A and B) can be found out by,
P(A and B) = P(A)
P(B)
Given that P(A) = 0.3 and P(B) =0.2
P(A and B) = 0.3
0.2
P(A and B)= 0.06
Thus the value of P(A and B) is 0.06
