Answer:
45(a + 2b)
Step-by-step explanation:
45a
step1 in order to factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...) The number of times that each prime divides the original integer becomes its exponent in the final result
Prime number 3 to the power of 2 equals 9 .
Prime number 5 to the power of 1 equals 5 .
90b
do the same as above
Prime number 2 to the power of 1 equals 2 .
Prime number 3 to the power of 2 equals 9 .
Prime number 5 to the power of 1 equals 5 .
Part I:
1. If you have to circle each outcome in the table that at least 1 die is a 4, then you have to circle row corresponding to the number 4 and column corresponding to the number 4.
2. If you have to cross out each outcome where the sum of the dice is greater than 5, then you have to cross out all not bold numbers 6, 7, 8, 9, 10, 11 and 12 in the table.
Part II:
Here you can see 36 possible outcomes.
1. The probability that at least 1 die is a 4 is:
- (favorable outcomes are 4+1=5, 4+2=6, 4+3=7, 4+4=8, 4+5=9, 4+6=10, 1+4=5, 2+4=6, 3+4=7, 5+4=9, 6+4=10).
2. The probability that the sum of the dice is greater than 5 is:
3. The probability that at least 1 die is a 4 and that the sum of the dice is greater than 5 is
4. The probability that at least 1 die is a 4 or that the sum of the dice is greater than 5 is:
