The term "three fifths" is equivalent to $\frac{3}{5}$ .
If $\frac{3}{5}$ of the cast is singing, then we just have to find the rest of the fraction.
$1- \frac{3}{5} \\ \frac{5}{5}- \frac{3}{5} \\ \frac{2}{5}$

Well, 3/5 of the cast is singing and the whole group would be 5/5 so then that makes 5/5 minus 3/5 which equals <em><u>2/5</u></em> don't have to sing!

artcher [175]

Answer:

12(3y+2x)

Step-by-step explanation:

In this question, we are asked to give an expression that represents the total cost of shorts for the players.

He is ordering 2 pairs of short and 3 shirts. Hence, per player, he would be spending the following:

2 pairs of shorts at x dollars each. Cost here is just $2x

3 shirts at y per one. Cost is $3y

Per player he is spending a total of 3y + 2x

Now, there are people to cater for. The total amount to spend will now be 12(3y + 2z )

Consider two people being randomly selected. (For simplicity, ignore leap years.)

inna [77]

Answer:

$(a) = \frac{144}{133225} \\\\(b) = \frac{1}{365}$

Step-by-step explanation:

Part (a) the probability that two people have a birthday on the 9th of any month.

Neglecting leap year, there are 365 days in a year.

There are 12 possible 9th in months that make a year calendar.

If two people have birthday on 9th; P(1st person) and P(2nd person).

$=\frac{12}{365} X\frac{12}{365} = \frac{144}{133225}$

Part (b) the probability that two people have a birthday on the same day of the same month

P(2 people selected have birthday on the same day of same month) + P(2 people selected not having birthday on same day of same month) = 1

P(2 people selected not having birthday on same day of same month):

$= \frac{365}{365} X \frac{364}{365} =\frac{364}{365}$

P(2 people selected have birthday on the same day of same month) $= 1-\frac{364}{365} \\\\= \frac{1}{365}$
