Sample space={5 B + 6 R + 9 G} = 20 (all possible outcomes
Favorable outcome ={6 R} = 6

P(1st Drawing R) = 6/20 = 3/10
Once drawn and not replaced the total remaining marble = 19 and within the 19, there are 5 Red left. So
P(2nd Drawing R) = 5/19 

P( 1st AND 2nd R) = (3/10)x(5/19) = 3/38 = 0.0789

soldi70 [24.7K]

Answer:

one forty fifth times five equals one ninth

Step-by-step explanation:

In division, the number being divided is the dividend or numerator, the denominator is the number we use to do the division while the result is the quotient and there may be a reminder.

For example, if

a/b = c

then

a = b * c

hence

1/9  ÷ 5

= 1/9 * 1/5

= 1/45

This means that

1/45 * 5 = 1/9

Hence the related multiplication equation related to the division equation one ninth ÷ 5 is one forty fifth times five equals one ninth
