The probability of writing a vowel is 0.5 (option b)
<h3>How to calculate the probability in this situation?</h3>
Probability is a way of measuring the certainty of occurrence of a specific event. Probability is measured from 1 to 0, with numbers closer to 1 referring to a higher chance and numbers closer to 0 referring to a lower chance.
According to the above, to calculate the probability we must perform the following operations:
- Calculate how many vowels and how many consonants are there in total? In the series of letters there are 3 vowels and 3 consonants.
- Later, we divide the number of vowels by the total number of letters to find the probability.
- 3 vowels ÷ 6 letters = 0.5 odds
Note: This question is incomplete because some information is missing. Here is the complete information
- The letter tiles shown below are in a bag. Without looking I am going to draw one tile. What are my chances of drawing a vowel?
- O,I,S,P,L,A
A.0.3
b.0.5
C.3
D.0.05

Answer:
Given that:
The equation for the future value of a deposit earning compound interest is equation:
.....[1]
where,
P = the initial deposit
t = years invested
r = rate at which interest is compounded annually
.
n = number of times the interest is compounded per year
As per the statement:
After 10 years, a $2,000-dollar investment compounded annually has grown to $3600.
⇒P = $2000 and V(t) = $3600
Substitute in [1] we have;
Divide both sides by 2000 we have;
Taking log base 10 both sides we have;
⇒
Divide both sides by 10 we have;
⇒
Simplify":
Subtract 1 from both sides we have;
or
r = 0.06 = 6%
Therefore, 6% is the interest rate to the nearest whole-number percent
Answer:
21 roads
Step-by-step explanation:
If each two cities are connected by a direct road, to find the number of roads we just need to solve a combination of 7 choose 2, that is, we need to find all pairs of two cities among the 7 cities:
Combination of 7 choose 2 = 7! / (5! * 2!) = 7*6/2 = 21
So there is a total of 21 roads on the island.
