Answer:
Irrational.
Step-by-step explanation:
√15 is irrational because although it can be written as a decimal, it cannot be written as a fraction, which is one of the main factors that defines what makes an irrational number.
The probability of a diamond is 13/52 = 1/4 So none of the diamonds can be used for the other 2 restrictions.
The even numbered cards are 2 4 8 10.
The 6 cannot be used, because it could come into the next category. Six is divisible by 3.
These can come from clubs hearts and spades.
So each even number has 3 suits it can come from
The number of cards in this category is 3 * 4 = 12
The probability of this occurring is 12/39 = 4/13
The cards divisible by 3 are
3 and 9 [Again you can't use the 6]
The Total number of cards are 2*3 = 6
The probability is 6/39 = 2/13
The total probability (without drawing a 6) is
1/4 + 2/13 + 4/13 = 37/52
The two categories where a 6 can turn up are equally likely so choosing the category is 1/2. the probability of a 6 turning up in the first category is 1/2* 3/39 = 3/78 = 1/26
The probability of the 6 turning up in the second category is 1/2 * 3/39 = 3/78 = 1/26 So these two numbers must added into the mix.
37/52 + 2(1/26) = 37/52 + 1/13 = 41/52

Answer:
201 students play basketball.
Step-by-step explanation:
total students who played sports = 347
58 % played basketball.
That is ,
Since number of students cannot be in decimals we take the nearest whole number = 201.
3(6x-8)-(-4x-7)
18x-24+4x+7
ANSWER= 22x-17
