Answer: 1/16
Step-by-step explanation: It's important to understand that the two spins are called independent events because the outcome of the first spin does not affect the outcome of the second spin.
To find the probability of independent events, we first find the probability of each event, then we multiply the probabilities together.
Since there is one 4 on the spinner and four possible outcomes, each of which is equally likely, the probability of spinning a 4 is 1/4.
This mens that 1/4 is the probability of
getting a 4 on the second spin too.
Now we multiply.
1/4 x 1/4 gives us 1/16.
So the probability of spinning a 4 twice is 1/16.
Answer:
Step-by-step explanation:
Given that total students =23.
15 have taken English, 13 Math and 8 both
number of students taking math only = total math - students who have taken both
= 13-8 = 5
Number of students taking English only = total English - students who have taken both
= 15-8 =7
Now we divided into 3 disjoint partitions as only Math, only English and both.
Thus no of students who have taken either math or english = 7+5+3 = 15
No of students who have taken neither = 24-15 = 9
