Question

In a group of 400 families, 300 own houses. If one family is randomly selected from ti
group the probability that this family owns a house is:
a) 75
b) 25
c) 80
d) 40​

Answer 1

Answer:

probability is 300/400=0.75=75%

hence option a is correct

Answer 2

Answer:

(A) 75% people have the probability of having a house.

Step-by-step explanation:

As per the question,

We need to find the probability that a random family owns a house.

As we know, Given data is that:

Total number of families in the group = 400

No. of families that own houses = 300

According to formula:

Probability = no. of favourable outcomes / total no of outcomes

So, for probability of random person owing house:

no. of favourable outcomes = 300

total no of outcomes = 400

Therefore, probability = $\frac{300}{400} = \frac{3}{4} \times 100 = 75\%$

So, the answer is that

(A) 75% people have the probability of having a house.
