Answer:
<h2>4/11</h2>
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
<em>Probability = expected number of outcome/Total number of outcome</em>
If there are group of 11 people, then the total outcome of events will be 11
If we are to select 4 oldest people from the group, then the expected outcome is 4.
Hence, the probability that the 4 oldest people in the group were selected is 4/11.
Answer: The 25th term of the sequence is 75
Step-by-step explanation:
The given sequence depicts an arithmetic progression. The consecutive terms differ by a common difference. We will apply the formula for arithmetic progression.
Tn = a + (n-1)d
Tn = The value of the nth term of the arithmetic sequence.
a = first term of the sequence.
d = common difference (difference between a term and the consecutive term behind it)
n = number of terms in the sequence.
From the information given,
a = 3
d = 5-3 = 7-5 = 2
We want to look for the 25th term, T25
So n = 25
T25 = 3 + (25-1)2 = 3+ 24×2
T25 = 3 + 72 = 75
