Convert the given time period to years, assuming a 360-day year. 9 months

Answers

Answer 1

Answer:

Answer:

0.75 years.

Step-by-step explanation:

Assuming 360 days in a year or 12 months.

So, we get $(360)/(12)=30$ days each month.

In 9 months there will be = $9*30=270$ days

So, convert this period to years = $(270)/(360)$ = 0.75 years.

Hence, the answer is 0.75 years.

Answer 2

Answer: .75 years, or 3/4ths of a year

A bag contains 2 red, 4 yellow, and 6 blue marbles.Two marbles are drawn at random. Find the portability that both are blue.

Answers

If two marbles are drawn at random, the probability that they are both blue is 1/4

The formula for calculating the probability is given as:

Probability = Expected outcome/Total outcome

Given that a bag contains 2 red, 4 yellow, and 6 blue marbles

Total outcome = 2 + 4 + 6 = 12 marbles

Since we are to find a probability of picking 2 blue balls

Pr(2 blue balls) = 6/12 * 6/12

Pr(2 blue balls) = 1/2 * 1/2

Pr(2 blue balls) = 1/4

Hence if two marbles are drawn at random, the probability that they are both blue is 1/4

Total number of marbles is 12, there are 6 blues.
When picking the first one the probability to pick the right one is $(6)/(12)=(1)/(2)$
When we pick the second one there are 11 marbles and only 5 blue so the probabilty is $(5)/(11)$

We need to pick 2 blues one after another so we multiply probabilities $(1)/(2)*(5)/(11)=5/22=0.227$ The probability is around 23%
