I roll a dice, what is the probability that I will roll a 3 or a 4?

1/3
0
1
3/4

1/2?

Step-by-step explanation:

if the die has the numbers 1, 2, 3, and 4 then 3 and 4 are the two numbers on top and 1 and 2 on the numbers on the bottom - 3 and 4 are the 2/4 of all the numbers, simplified, it is 1/2.

A) 73.6%

Step-by-step explanation:

The computation of the percentage is shown below

Given that

W = Woe^{-0.09t}

After 34 days

W = W_oe^{-0.009×34}

= 0.736W_o

Now the percentage is

= 0.736 × 100

= 73.6%
