Answer:
B. 0.03110
Step-by-step explanation:
Given
Probability of Hit = 60%
Required
Determine the probability that he misses at 6th throw
Represent Probability of Hit with P
Convert to decimal
Next; Determine the Probability of Miss (q)
Opposite probabilities add up to 1;
So,
Substitute 0.6 for p
Next,is to determine the required probability;
Since, he's expected to miss the 6th throw, the probability is:
Hence;
<em>Option B answers the question</em>
Answer:
1.5
Step-by-step explanation:
Numbers in the interval are 0, 1, 2 and 3
Average Value = (0+1+2+3)/4=1.5
Answer:
Step-by-step explanation:
We can make the conversion from mixed numbers to improper fractions:
- Multiply the whole number part by the denominator of the fraction.
- Add the numerator of the fraction and the product obtained (This sum will be the new numerator).
- The denominator is the same.
Then:
We need to add these fractions in order to calculate how far Erin jogged, we must find the Least Common Denominator (LCD):
Then, the sum is:
To convert this improper fraction to a mixed number:
- When you divide 33 by 4, you get a quotient of 8. This will be the whole number.
- The remainder obtained is 1. This will be the numerator of the fraction.
- The denominator does not change.
Therefore, you get:
