Question

is it possible to have a probability as 15%
​

Answer 1

Answer:

yes its possible to have a probability of 15%

Step-by-step explanation:

Answer 2

Answer:

Step 1: Find the number for both the events in the question happening together. In our sample, question, we were asked for the probability of no + male. From the table, the number of males is 25.

Step 2: Divide your answer in step 1 by the total figure. In our example, it’s a survey, so we need the total number of respondents (100, from the table).

25 / 100 = 0.25

Step 3: Identify which event happened first (i.e. find the independent variable). In our example, we identified the male subgroup and then we deduced how many answered no, so “total number of males” is the independent event. The question usually gives this information away by telling you “given that the respondents were male…” (as in our question).

Step 4: Find the probability of the event in Step 3. In our example, we want the probability of being a male in the survey. There are 40 males in our survey, and 100 people total, so the probability of being a male in the survey is 40 / 100, or .4.

Step 5: Divide the figure you found in step 2 by the figure you found in step 4.

.25 / .4 = 0.625
