A bag contains 33 red marbles, 6 white marbles, and 5 gray marbles. You randomly pick out a marble, record its color, and put it

Ksju [112]

<h3>Total 73 times we can expect white or gray marbles.</h3>

Step-by-step explanation:

Total number of marbles = 33

Number of white marbles = 6

Number of gray marbles = 5

Now, as we need to pick white or gray marbles, so favorable outcomes

= 6+ 5 = 11 marbles

Now, P(Picking out 1 white or gray marble) = $\frac{\textrm{Total Favorable outcomes}}{\textrm{Total Outcomes}} = \frac{11}{33} = (\frac{1}{3})$

Here, the same experiment is repeated 220 times.

So, the Combined Prediction

= Probability at first attempt x Number of repetitions

$= (\frac{1}{3} ) \times 220 = \frac{220}{3} = 73.33 \approx 73$

⇒The combined prediction after 220 attempts = 73

Hence, total 73 times we can expect white or gray marbles.

Suppose that two cards are randomly selected from a standard 52-card deck. (a) What is the probability that the first card is

ser-zykov [4K]

Answer:

(a) $\frac{1}{17}$ (b) $\frac{1}{16}$

Step-by-step explanation:

GIVEN: Suppose that two cards are randomly selected from a standard $52$ card deck.

TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without replacement? (b) What is the probability that the first card is a club and the second card is a club if the sampling is done with replacement.

SOLUTION:

(a)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{13}{52}$

$=\frac{1}{4}$

As sampling is done without replacement.

probability that second card is club $P(B)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{12}{51}$

$=\frac{4}{17}$

Probability that first card is club and second card is club $=P(A)\times P(B)$

$=\frac{1}{4}\times\frac{4}{17}=\frac{1}{17}$

(b)

Probability that first card is club $P(A)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{13}{52}$

$=\frac{1}{4}$

As sampling is done with replacement.

probability that second card is club $P(B)=\frac{\text{total club cards}}{\text{total cards}}$

$=\frac{13}{52}$

$=\frac{1}{4}$

Probability that first card is club and second card is club $=P(A)\times P(B)$

$=\frac{1}{4}\times\frac{1}{4}=\frac{1}{16}$

Sorry before it didn't came

zavuch27 [327]

Answer:

220

Step-by-step explanation:

If we take 20 common (as in we can take it out and group the rest) , we can say 20 (15 7/9-4 7/9) which is equal to 20 (11). 20x11 = 220.

If DE = 7x + 3 and EF = 9x - 19,<br> then EF = ?

ANEK [815]

Answer:

Step-by-step explanation:

7x + 3 = 9x - 19

-2x + 3 = -19

-2x = -22

x = 11

DE= 7(11) + 3 = 77 + 3 = 80

EF = 9(11) - 19 = 99 - 19 = 80

80 + 80 = 160 for DF
