Answer:

11,8,5

Step-by-step explanation:

an=11-3(n-1)

Let n=1

a1 = 11 - 3(1-1)

= 11 -0

=11

Let n=2

a2 = 11-3(2-1)

= 11 -3(1)

= 8

Let n=3

a3 = 11-3(3-1)

= 11 -3(2)

= 11 -6

Answer:

5/12

Step-by-step explanation:

The probability of rolling a number greater than 1 is 5/6, because 5 numbers on a 6-sided dice are greater than 1.

The probability of rolling an even number is 3/6, because 3 numbers on a 6-sided dice are even numbers.

$5/6 \times 3/6$

$=15/36$

$=5/12$
