Out of 450 applicants for a job, 206 are male and 62 are male and have a graduate degree.

xxMikexx [17]

Answer:

0.3009 is the probability that the applicant has graduate degree given he is a male.

Step-by-step explanation:

We are given he following in the question:

M: Applicant is male.

G: Applicant have a graduate degree

Total number of applicants = 450

Number of male applicants = 206

$n(M) = 206$

Number of applicants that are male and have a graduate degree = 62

$n(M\cap G) = 62$

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

$P(M) = \dfrac{206}{450} = 0.4578$

$P(M\cap G) = \dfrac{n(M\cap G)}{n} = \dfrac{62}{450} = 0.1378$

We have to find the probability that the applicant has graduate degree given he is a male.

$P(G|M) = \dfrac{P(G\cap M)}{P(M)} = \dfrac{\frac{62}{450}}{\frac{206}{450}} = \dfrac{62}{206} = 0.3009$

Thus, 0.3009 is the probability that the applicant has graduate degree given he is a male.

The Baltimore Marathon features a relay race.

Kazeer [188]

Answer:

$S = 149\ min$

$S = 2\ hr\ 29\ min$

Step-by-step explanation:

Let S be the sum of the times for all winning team.

Given:

leg 1. 32 minutes 56 seconds.

leg 2. 42 minutes 28 seconds.

leg 3. 34 minutes 34 seconds.

leg 4. 39 minutes 2 seconds

We need to find the total time to run all four legs of the marathon.

Solution:

Sum of the times for all winning team.

$Sum\ of\ the\ times = leg\ 1 + leg\ 2 + leg\ 3 + leg\ 4$

Substitute running times for all legs.

$S = 32\ min\ 56\ sec+ 42\ min\ 28\ sec + 34\ min\ 34\ sec + 39\ min\ 2\ sec$

Now, we write the minutes and seconds separately.

$S = (32+42+34+39)min+(56+28+34+2)sec$

$S = (147)min+(120)sec$

$120\ sec =\frac{120}{60} = 2\ min$

$S = (147)min+(2)min$

$S = 149\ min$

Therefore, Total time taken by all four legs $S = 149\ min$ or $S = 2\ hr\ 29\ min$ .
