Abag contains 8 red, 4 blue, and 4 yellow marbles. what is the probability of randomly choosing 2 blue marbles without replacement? write the answer as a decimal. round to the nearest hundredth if needed. and what is the probability of getting heads, tails, and heads, in that order when flipping a coin? are these events dependent or independent? a. 1/8 dependent b. 1/8 independent c. 1/6 dependent d. 1/6 independent. me i really need it you so much for whoever me.

The probability of randomly choosing 2 blue marbles without replacement is .

B. The probability of getting heads, tails, and heads, in that order when flipping a coin is 1/8.

These events are independent.

Step-by-step explanation:

Given: The number of blue marbles in the bag = 4

The total number of marbles in the bag =

After choosing one marble, the total marbles remains in the bag =

If first marble is blue, then number of blue marbles in bag =

Now, the the probability of randomly choosing 2 blue marbles without replacement is given by :-

Hence, the probability of randomly choosing 2 blue marbles without replacement is .

In order when flipping a coin.

Total outcomes = 2

Then, the probability of getting heads, tails, and heads, in that order when flipping a coin is given by :-

These events are independent of each other because the next event is not affected by the previous event.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

answer: 20
