Answer:
The sum of the digit of the product is 13
Step-by-step explanation:
Given
Solving (a): The product
Solving (b): The sum of the digits
Since order does not matter, you use a combination and not a permutation, so the first one is true, which means the second one is not true.
The probability of choosing two diamonds and three hearts can be represented by (13C2 * 13C3)/52C5, which is 0.0086, not 0.089, so the third one is not true.
The probability of choosing five spades and the probability of choosing five clubs are represented by the same thing, 13C5/52C5, which is roughly 0.0005, so the fourth one is not true but the fifth one is. So the answer is the first and fifth one.
2 1/6
multiply the fraction to see the answer. if you multiply 4 and 1 third by three sixth you get 2 3/18 which is the same as 2 1/6.
