<h3>Answer:  12/51 (choice A)</h3>

===========================================================

Explanation:

"Given that a diamond was drawn on the first draw and not replaced" means we know 100% that there are P = 13 - 1 = 12 diamonds left out of Q = 52-1 = 51 cards overall.

The probability of picking another diamond card is therefore P/Q = 12/51

This only works if the card is not replaced. If the card is replaced, then the probability would be 13/52 = 1/4.

pshichka [43]

Answer:

B. 0.03110

Step-by-step explanation:

Given

Probability of Hit = 60%

Required

Determine the probability that he misses at 6th throw

Represent Probability of Hit with P

P = 60\%

Convert to decimal

P = 0,6

Next; Determine the Probability of Miss (q)

Opposite probabilities add up to 1;

So,

p + q = 1

q = 1 - p

Substitute 0.6 for p

q = 1 - 0.6

q = 0.4

Next,is to determine the required probability;

Since, he's expected to miss the 6th throw, the probability is:

Probability = p^5 * q

Probability = 0.6^5 * 0.4

Probability = 0.031104

Hence;

<em>Option B answers the question</em>

If the range of the function f(x) = 4x – 3 is {11.4, 15, 17, 29}, what is its domain?
malfutka [58]
The range of the function is the y-component or the ordinate of the sets of points. The domain of the function meanwhile is the x-component ot the abscissa of the sets of points. In this case, we have the function <span>f(x) = 4x – 3 and given each y, we get the x. Subsituting each y to the function we get the domain equal to {3.535, 4.5, 5, 8}.</span>
