Chance of finding a bug = 0.35
Chance of not finding a bug = 1 - 0.35 = 0.65
Probability of finding a bug in the first 3 programs =
Probability of not finding a bug in 2 out of the 3 and finding a bug in 1.:
0.65^2 * 0.35 = 0.147 = 0.15
Answer is A.
2.
Probability of heads = 0.50
Probability of tails = 0.50
Probability of heads on the fourth attempt = tails x tails x tails x heads = 0.5 x 0.5 x 0.5 x 0.5 = 0.0625
The answer is B.

Answer:
The value of the expression is 2
Step-by-step explanation:
Find the complete question in the attachment.
From the attachment, we are to rearrange the numbers 1, 2, 3, 4, 5 and 6 into the boxes given and get a number closer to zero.
The expression will be in the format below:
a•xⁿ - b(c+d)
Taking a= 1, x = 2, n = 5, b = 3, c=4 d= 6
On substituting
= 1•2^5 - 3(4+6)
= 1•(32) - 3(10)
= 32-30
= 2
Since 2 is greater than 0, hence the arrangements will be first box takes 1, second takes 2, third box takes 5, fourth box takes 3, fifth box takes 4 and sixth box takes 6.
Answer / Step-by-step explanation:
In this exercise, we know that the agency collected 1,829 bullets which according to the agency, all came from different source.
The number of pair of bullet is :
(1,829) = 1, 829 ! / 2! ( 1,829 - 2 ) = 1, 829 x 1,828 x 1827 ! / 2 x 1 x 1,827
( 2 )
= 6, 108,413,724 / 3654
= 1671,706.
Also, we know that the agency found 658 matches. According to this, the chance of false positive ( that is, the agencies find a match but the bullets are from two different source ) is
P (False positive ) = 658 / 671,706
= 0.000979.
The probability is small to an extent, therefore, we should have confidence in the agency forensic report and evidence
It’s gonna be (E because - bigger then 2
