4. A game consists of spinning an arrow which comes to rest pointing at
one of the numbers 1.2.3,4,5,6,7.8.9, 10, 11, 12; as shown below.
Ir the outcomes are equally likely, find the probability that the pointer
will point at:
a) 6
b) an even number
c) a prime number
d) a number greater than 8.
e) a number less than or equal to 9
1) a number between 3 and 11.​

Answer 1

Answer:

e) a number less than or equal to 9

Answer 2

Answer:

Hello user,

The answer of these questions has been mentioned below :-

Step-by-step explanation:

(a) p(n) =6/12

--> 2

(b) a every no. = probability of getting a even no.

total no. of outcome =2+4+6+8+10+12= 42

no. of outcome =12

so, p(n) = 42/12 =3.5

(d) a no. greater than 8= probability of getting greater than 8

total no. of outcome greater than 8= 9+10+11+12=42

no. of outcome =12

so, p(n) =42/12=3.5

(e) a no. less than or equal to 9= probability of less than or equal to 9

total no. of outcome =1+2+3+4+5+6+7+8+9=45

no. of outcome =12

so, p(n) =45/12=3.7

hope, you got some answers of your questions.
