At the playground, the new sandbox was 3 meters wide and 2 meters long. what is the area of the sandbox

area = length times width

area = 2 meters * 3 meters

area = 6 m^2

Option b.) 0.245 would be correct.

Step-by-step explanation:

There is given two probabilities events  occurring simultaneously

we have to find  the probability that Nathan is not allergic to penicillin and the test predicts it.

As, Nathan has a 75% chance of having the same allergy.

Hence, (100-75)%=25% = 0.25 chance of not having the same allergy

The probability that the test is accurate: 98% = 0.98.

By using the multiplication rule -

25% × 98% = 0.25 × 0.98 = 0.245

Therefore the probability after the test that Nathan is not allergic to the drug would be 24.5% or 0.245.
