The probability of getting two red lenses when two are selected will be 2/13.
<h3>What is probability?</h3>
The probability of favorable events to the total number of occurrences.
A box contains four red, three blue, and six green lenses.
Two lenses are randomly selected from the box.
Then the probability of getting two red lenses when two are selected if the first selection is not replaced before the second selection is made will be
The total number of the event will be
Total event = ¹³C₂
Total event = 78
Then the favorable event will be
Favorable event = ⁴C₁ x ³C₁
Favorable event = 4 x 3 = 12
Then we have
P = 12 / 78
P = 2/13

Answer:
4.8 minutes
Step-by-step explanation:
2.5/2.5=1
so
12/2.5=4.8
Hey there!
When we solve for x, we need to isolate x on one side.
This is just a one-step equation, meaning there is only one thing we need to do to solve for x, or isolate x.
Starting with 87 + x = 100:
Subtract 87 from each side.
87 <u>- 87</u> + x = 100 <u>- 87</u>
Simplify. Subtracting 87 from 87 makes it equal to 0.
x = 13
Your answer is A. 13.
Hope this helps!

Answer:
circumference of a circle is equal to π (22/7)×diameter of a circle
Answer:
300 × (1 + 0.10)^n
Step-by-step explanation:
The computation is shown below:
Given that
The population is 300
And, the population would be increased at a rate of 10% each year
So, the exponential growth function to calculate the daily growth rate is
= 300 × (1 + 0.10)^n
Here n represent the number of years or the time period
So, the above show the exponential growth function
