An employer has a staff of eighty actuaries, ten of whom are student actuaries. A student actuary is allowed a total of ten week

sergiy2304 [10]

Answer:

0.1111

Step-by-step explanation:

From the given information;

Number of staffs in the actuary = 80

Out of the 80, 10 are students.

i.e.

P(student actuary) = 10/80 = 0.125

number of weeks in a year = 52

off time per year = 10/52 = 0.1923

P(at work || student actuary) = (50 -10/52)

= 42/52

= 0.8077

P(non student actuary) = (80 -10)/80

= 70 / 80

= 0.875

For a non-student, they are only eligible to 4 weeks off in a year

i.e.

P(at work | non student) = (52-4)/52

= 48/52

= 0.9231

∴

P(at work) = P(student actuary) × P(at work || student actuary) + P(non student actuary) × P(at work || non studnet actuary)

P(at work) = (0.125 × 0.8077) + ( 0.875 × 0.9231)

P(at work) = 0.1009625 + 0.8077125

P(at work) = 0.90868

Finally, the P(he is a student) = (P(student actuary) × P(at work || student actuary) ) ÷ P(at work)

P(he is a student) = (0.125 × 0.8077) ÷ 0.90868

P(he is a student) = 0.1009625 ÷ 0.90868

P(he is a student) = 0.1111

Out of 49 fish 31 are goldfish. About what percent are gold fish?

myrzilka [38]

63.27 % of fishes are gold fish

<h3><u>Solution:</u></h3>

Given that out of 49 fish, 31 are goldfish

To find: percent of gold fish

The percent of gold fish is calculated by dividing number of goldfish by total number of fish multiplied by 100

<em><u>The percentage of gold fish is given by formula:</u></em>

$\text{percent} = \frac{\text{number of gold fish}}{\text{total number of fish}} \times 100$

From given information,

total number of fish = 49

number of gold fish = 31

Substituting the values in formula, we get

$percent = \frac{31}{49} \times 100\\\\percent = 0.6326 \times 100 = 63.27$

Therefore, approximately 63.27 % of fishes are goldfish
