A number is chosen at random from 1 to 50. Find the probability of selecting either a multiple of 4 or a multiple of 5.
Answers
Answer:
Please mark me as a brilliant answer
Step-by-step explanation:
Let say the random number be x which is between 1 and 50
Now let's list multiple of 4s upto 50
4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
Similarly multiple of 5s
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
20 and 40 see common numbers,, total 20 distinct/ unique numbers are available between 1 and 50, which are either multiples of 4 or multiples or 5.
20/50 is probability
=2/5
=0.4 i.e., 40% is the probability of a random number chosen between 1 and 50 could be multiple 4 or 5
Answer:
The Probability of selecting either a multiple of 4 or a multiple of 5 is 20/50 or 2/5
Step-by-step explanation:
Let say the random number be x which is between 1 and 50
Now the numbers which are multiple of 4s upto 50
4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
Similarly the numbers which are multiple of 5s
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
20 and 40 see common numbers,, there are total of 20 distinct/ unique numbers are available between 1 and 50, which are either multiples of 4 or multiples or 5.
So therefore We know the formula of Probability
P(E) = favorable outcomes/ total outcomes
Favourable outcomes = 20
Total outcomes = 50
20/50 is probability
=2/5
=0.4 i.e., 40% is the probability of a random number chosen between 1 and 50 could be multiple 4 or 5
