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}

The ratio of the surface areas of two similar solids is 4:49. What is the ratio of a volumes?
Fynjy0 [20]

Answer: 8/343

Step-by-Step:

If two similar solids have a scale factor of a:b then,

The ratio of their surface areas (2D) is- a^2:b^2

The ratio of their volume (3D) is- a^3:b^3

First you want to square root the scale factor numbers to find the original value. Then you cube the original numbers to find the answer.

B(1)= 160, b(n) = b(n-1) * 0.5 for n (g/e) 2 determine the first 4 items in a sequence given this recursive formula.
Paul [167]

Answer:

160

80

40

20

Step-by-step explanation:

You start with the first term that is given which would be

b(1)=<u><em>160</em></u>

That would be our first term, then we multiply by 0.5 which would be 1/2

which gives us 80 as it is a division

You take the next term that we have found (80) and then we do the same thing, multiply by 0.5 (1/2)
