Jerome is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability tha

alexira [117]

Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.

Event A - get a green or yellow marble
Event B - get a pink marble

Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.
$P(A)= \frac{3+4}{3+4+5+8}= \frac{7}{20} 
\\P(B)= \frac{8}{3+4+5+8}= \frac{8}{20} = \frac{2}{5}$

Probability of combined events is
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$

The domain of a sequence can include decimals and irrational numbers.<br> A. True<br> B. False

LenKa [72]

Given statement is that "The domain of a sequence can include decimals and irrational numbers."

Noow we have to decide if that statement is True or False.

We know that position of any term of any sequence is denoted like 1st tem, 2nd term, third term,... nth term.

In that situation we always use positive integers but not the decimal or irrational numbers.

So it is obvious that domain of tthe sequence can't include decimal and irrational but that should be positive integer.

Hence final answer is FALSE.
