1.
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.
Step-by-step explanation:
Tax charge
80 × 6.75/100 = 5.4
Cost + tax charge
80 + 5.4 = 85.4
Tip (15% of cost and tax)
85.4 × 15/100 = 12.81
(Cost + tax charge + tip)
85.40 + 12.81 = 98.21
therefore, $95 is not enough.

Answer:
D
Step-by-step explanation:
Labor productivity is is measured per hours.
Hence, the work he does [amount of claims] will be distributed amongst the amount of hours he works. The amount of dollar he uses <em>doesn't matter for labor productivity.</em>
<em />
Thus, his work is 6 claims. He does that is 8 hours. So claim/hr is:
6/8 = 0.75 claims per hour
Answer choice D is right.
Answer:
2/29
Step-by-step explanation:
If 9 play none, of the 29 students, 29-9 =20 play at least one. If 14 play basketball, then 20-14 = 6 play only baseball. Since 8 play baseball, there must be 8-6 = 2 who play both baseball and basketball.
Choosing at random, the probability is 2/29 that a student will be chosen who plays both sports.
