Answer:

Step-by-step explanation:

Given that:

Batting average = 0.25 after 160 times at bat;

Batting Average = Number of hits / number of times at bat

0.25 = number of hits / 160

Number of hits = 0.25 * 160 = 40

He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average

Hence,

New average = number of hits / number of times at bat

0.333 = (number of hits + x) / (160 + x)

0.333 = (40 + x) / (160 + x)

From a shipment of 65 transistors, 6 of which are defective, a sample of 5 transistors is selected at random.
Vladimir79 [104]

Answer:

a) 8259888

b) 34220

c) 45057474

Step-by-step explanation:

Given,

The total number of transistor = 65,

In which, the defective transistor = 6,

So, the number of non defective transistor = 65 - 6 = 59,

Since, out of these transistor 5 are selected,

a) Thus, the number of ways = the total possible combination of 5 transistors = {65}C_ 5

=\frac{65!}{(65-5)!5!}

=8259888

b) The number of samples that contains exactly 3 defective transistors = the possible combination of exactly 3 defective transistors = {6}C_3\times {59}C_2

=\frac{6!}{(6-3)!3!}\times \frac{59!}{(59-2)!\times 2!}

=20\times 1711

=34220

c) The number of sample without any defective transistor = The possible combination of 0 defective transistor = ^6C_0\times ^{59}C_5

=1\times 45057474

=45057474
