Colby is testing the effectiveness of a new allergy medication. there are 100 people with allergies in the study. sixty-two patients received the allergy medication, and 38 other patients did not receive treatment. fifty of the patients who received the medication reported no allergies at the end of the study. twenty of the patients who did not receive medication reported no allergies at the end of the study. what is the probability that a patient chosen at random from this study took the medication, given that they reported no allergies?

Step-by-step explanation:

Here, the size of sample space = 100 patient.

Let M shows the event that the patients received the allergy medication,

M' shows the event that the patients do not received the allergy medication,

And, N shows the event that the patient does not has the allergy.

Thus, According to the question,

( Because, Total number of patient who do not have allergy = total patients who received the medication reported no allergies at the end of the study + total patients who did not receive medication reported no allergies at the end of the study)

Thus, the probability that a patient chosen at random from this study took the medication, given that they reported no allergies,

⇒

answer: b f g .

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
