The top one (keep in mind i think)
42 players are on teams in all and that each team has 6 players. This is correct if the number 7 is referring to the number of teams.
Answer: 1/12
Step-by-step explanation:
First make all the fractions have the same denominator. To do that, multiply the fractions by a number that will get them the same denominator. In this case, multiply 1/4 by 3, and 2/3 by 4.
1/4 x 3/3 = 3/12
2/3 x 4/4 = 8/12
then you have 3/12 + 8/12 = 11/12
so, blue is 1/12

Answer:
10/33
Step-by-step explanation:
The usual approach (if your calculator won't do this for you) is to convert the mixed number to an improper fraction, then perform the division. That division can be accomplished by multiplying the numerator by the inverse of the denominator.
1 7/15 = (15+7)/15 = 22/15
Then ...
(4/9)/(22/15) = (4/9)(15/22) = (2·2·3·5)/(3·3·2·11) = (2·5)/(3·11) = 10/33
_____
<em>Alternate solution</em>
Both fractions can be given the same denominator:
4/9 = 20/45
1 7/15 = 22/15 = 66/45
Now, the division is ...
(20/45)/(66/45) = 20/66 = 10/33
I suspect you want the area under the standard normal curve to the left of z = -0.95.
On my calculator I typed in normal cdf(-100, -0.95) and got the result 0.171.
