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:
94
Step-by-step explanation:
Given, the ratio of blocks A, B, C,D are in the ratio 4:7:3:1
Let us consider the common ratio to be ‘x’.
So, toy blocks with alphabet A is 4x and
toy blocks with alphabet B is 7x and
toy blocks with alphabet C is 3x and
toy blocks with alphabet D is x
Again, the number of ‘A’ blocks is 50 more than the number of ‘C’ blocks.
As no. of ‘A’ and ‘C’ blocks are 4x and 3x respectively.
So,
4x=50 + 3x
x=50
Thus, the number of ‘B’ blocks is 7x = 7(50) = 350
350 is the required number.
