$\\ \rm\Rrightarrow 3100.5=10.6(15)B$

$\\ \rm\Rrightarrow 3100.5=159B$

$\\ \rm\Rrightarrow B=\dfrac{3100.5}{159}+19.5$

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
$P(A) \times P(B)=\frac{7}{20} \times \frac{2}{5} =\frac{7}{50}$

Ellen claims she has a coin that is weighted so that the probability of heads is 70%.

kvasek [131]

Outcome Heads Tails
Relative Frequency 0.69 0.31

so first statement is false as 69% is close to 70%.

second statement is false as heads probability is close to 70%

last 2 statements are true:

The theoretical probability of tails is most likely 30%.

It is likely that the coin is not fair.

PLEASE HELP I WILL GIVE BRAINLEST

Ira Lisetskai [31]

The theoretical probability of getting heads or tails is 1/2 the time.

1/2 of 150 = 75

So theoretically you would get 75 heads and 75 tails.

The experiment got 84 heads, which is greater than 75, so it would be higher than the theoretical probability.

The answer is : It is 6% higher than the theoretical probability.
