There are 4 blueberry, 6 raisins, and 2 plain bagels in a bag. Mike randomly selects two bagels without replacing the first bage
rodikova [14]

Answer:

The probability that he selects a raisin bagel and then a plain bagel is \frac1{11}.

Step-by-step explanation:

Probability:

The ratio of the number of outcomes of favorable event to total number of all possible outcomes is called probability of the favorable event.

Probability=\frac{\textrm{The number of favorable outcomes}}{\textrm{Total number of all possible}}

Given that, there are 4 blueberry, 6 raisins and 2 plain bangles in a bag.

Total number of bangles= (4+6+2)

                                        = 12

The probability that he selects a raisin

=\frac{\textrm{Number of raisin bangles}}{\textrm{Total number of bangles}}

=\frac{6}{12}

=\frac12

Total number of remaining bagels is =(12-1)=11

After selecting a raisin  bagel,the probability that he selects a plain bangle is

=\frac{\textrm{Number of plain bangles}}{\textrm{Total number of bangles}}

=\frac{2}{11}

Selecting of a raisin bangle and a plain bangle are both independent event.

The probability that he selects a raisin bagel and then a plain bagel is

=\frac{1}2\times\frac{2}{11}

=\frac1{11}

In a video game, Val scored 30%, percent fewer points than Peeta. Peeta scored 1060 points.
katen-ka-za [31]

Answer:

742

Step-by-step explanation:

Divide 1060 by 10 to get 106. This is 10% of his score.

100-30 is 70, so Val scored 70% of Peeta’s points.

Multiply 106 by 7 find 70%

Val scored 742 points
