The answer is 1/10.
There are in total 20 marbles in the bag:
3 green + 2 yellow + 6 blue + 9 red = 20 marbles
There are 2 yellow marbles of total 20 marbles. 2 of 20 can be expressed as:
2/20 = 1/10.
Therefore, <span>the probability of picking a yellow marble from the bag is 1/10.</span>
To make things easier, convert the mixed number 12 1/2 into a fraction.
12 1/2 = 25/2
1/3 x 25/2 = 25/6
Answer:
(B) 0.0588
Step-by-step explanation:
The probability is calculated as a division between the number of possibilities that satisfy a condition and the number of total possibilities. Then, the probability that the first card is diamonds is:

Because the deck has 52 cards and 13 of them are diamonds.
Then, if the first card was diamonds, the probability that the second card is also diamond is:

Because now, we just have 51 cards and 12 of them are diamonds.
Therefore, the probability that both cards are diamonds is calculated as a multiplication between
and
. This is:

3.92/2.8=1.4
Unless it’s reverse.
2.8/3.92=0.714285714285 and so on.
30 x 20=600
your answer is that he would type 600 words in 20 minutes.
