Answer:

Step-by-step explanation:
Let the probability of an even number occurring be p and that of odd be q. From the question, p = 2q.
Now, p and q are mutually exclusive events. Hence,
p + q = 1
2q + q = 1
3q = 1
q = 1/3
p = 2q = 2/3
There are 3 odd numbers and 3 even numbers on a die. The probability of each even number is p/3 = 2/9 and the probability of each odd number is q/3 = 1/9.
The event E is the event of a 3, 2 or 1 appearing. Here, we have two odd numbers and 1 even number.

2/3 cup = 80 calories
1/3 cup = 80 ÷ 2 = 40
3/3 cup = 40 x 3 = 120 calories
1/2 cup = 120 ÷ 2 = 60 calories
A cup and a half = 120 + 60 = 180 calories
Answer:
Step-by-step explanation:
Given the inequality
0.21x + 0.05(17 - x) > 2.55 where x is the amount of 21% lotion needed
Given
0.21x + 0.05(17 - x) > 2.55
Open the parenthesis
0.21x + 0.85-0.05x > 2.55
Collect like terms
0.21x-0.05x+0.85>2.55
0.16x+0.85>2.55
0.16x>2.55-0.85
0.16x > 1.7
x > 1.7/0.16
x > 10.625
Hence she will need 21% lotion approximately greater than 10 ounces
