Answer:
The correct option is (B).
Step-by-step explanation:
The conditional probability of an event, say <em>A</em> is the probability of that events (A) when it is known that another event, say <em>X</em> has already occurred.
For example, consider the experiment of drawing two marbles from jar consisting of 8 white and 2 red, without replacement. The probability of selecting a red marble after a white marble is known as conditional probability.
In this case it is provided that:
- 40% of the students are licensed drivers
- 55% students are female.
The statement:
"the probability that a student who is a licensed driver is a male"
Is a statement of conditional probability.
This is because it is known from previous information that the student is a licensed driver and we need to determine the probability of this student being a male.
Thus, the correct option is (B).
Answer:
48.
Step-by-step explanation:
Given, Henrey bakes 84 bread rolls and fruit muffins.
Let, Henrey baked x bread rolls, then he baked y fruit muffins. according to the second condition,
(x - 18) = 5/6 y
Now, solving these two equations,
y = 84-x
Or, x-18 = 5/6 (84-x)
Or, 6x- 108= 420-5x
Or, 11x= 528
Or, x= 48
Now, y= 84- 48= 36
Thus, Henry baked 48 rolls and 36 fruit muffins.
Answer: The answer would be
D - 12.25x + 3.99 = 77.49
Step-by-step explanation:
If each shirt costs $12.25, that would be 12.25 times “x” amount of shirts. Then, you add the $3.99 shipping amount. Which all equals 77.49.
Answer:
8^5 (32768)
Step-by-step explanation:
Hi!
Remember that 8 is basically 8^1.
When we divide by exponents, we subtract the bottom exponent from the top one.
In this case, our expression looks like this.
6-1 = 5, so our answer is 8^5, or 32768.
8 + n ÷ 3 = -2
-8 -8
n ÷ 3 = -10
*3 *3
n = -30
