5. There are 396 persons in a theater. If the ratio of women to men is 2:3, and the ratio of men to
defon

Answer:

The number of men = 108

Step-by-step explanation:

Total person = 396

ratio of women to men = 2:3

ratio of men to children = 1:2=2:4=3:6

Women = 2

Men = 3

Children = 6

Hence,

women+men+children = 2+3+6 = 11

Now finding out the percentage of each

Women = 2/11 * 396

= 792/11

=72

Men = 3/11 * 396

=1188/11

=108

Children = 6/11 *396

=2376/11

=216

Thus the number of men = 108 ....

A game is played, where a die is tossed and a marble selected from a bag. Bag M contains 3 red marbles (R) and 2 green marbles (
Vinvika [58]

Answer:

2/3

Step-by-step explanation:

A die has 6 sides.  If a 3 or 5 is rolled, then bag M is selected.  So the probability that bag M is selected is 2/6 = 1/3.

Likewise, if a number other than 3 or 5 is rolled, then bag N is selected.  So the probability that bag N is selected is 4/6 = 2/3.

If bag M is selected, the probability the marble is green is 2/5.  The probability that M is selected, AND the marble is green, is therefore:

(1/3) (2/5) = 2/15

If bag N is selected, the probability that the marble is green is 8/10 = 4/5.  The probability that N is selected, AND the marble is green, is therefore:

(2/3) (4/5) = 8/15

The total probability that a green marble is selected is therefore:

P = 2/15 + 8/15

P = 10/15

P = 2/3
