9/25 = 0.36

B) Fraction to decimal conversion:
4/16 = 2/8 = 1/4 = 0.25

Use long decision or a calculator - 1 divided by four

C) Again, 9/25 = nine divided by twenty-five = 0.36

Robin rolled a die and then flipped a coin. What is the probability she rolled an even number and the coin landed on heads?
aleksandr82 [10.1K]

Answer:

1/4

Step-by-step explanation:

There are 3 even numbers of the 6 numbers on a die.

(1,2,3,4,5,6) are the possible numbers.  2,4,6 are even

P( even number ) = 3/6 = 1/2

P (heads) = 1/2

Since they are independent events, we can multiply the probabilities together

P (even, heads) = 1/2 * 1/2 = 1/4
