Answer:
a) P = 2/7
b) P = 4/7
c) P = 1/7
Step-by-step explanation:
In the range of [2,8], we have the following integers which are: 2, 3, 4, 5, 6, 7, 8. So this is a total of 7 integers.
a) We look for the probability that the numbers are less than 4, so we conclude that there are possible numbers 2 and 3 out of possible 7, so the required probability is equal to P = 2/7.
b) We look for the probability that the numbers are greater than 4, so we conclude that there are possible numbers 5, 6, 7, 8 out of possible 7, so the required probability is equal to P = 4/7.
c) Based on the previous two examples, we conclude that the required probability is P = 2/7· 1/2=1/7.
The equation for volume of a sphere is pi(r)^3 This mean that the equation would be pi(11)^3 which equals 1331pi
The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.
<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
The expression is given below.
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
Simplify the equation, then the value of the expression will be
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
⇒ (7 x 10⁻¹³) − (0.042 x 10⁻¹³)
⇒ 6.958 x 10⁻¹³
The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.
