When you calculate probability, you're attempting to figure out the likelihood of a specific event happening, given a certain number of attempts. Probability is the likliehood that a given event will occur and we can find the probability of an event using the ratio number of favorable outcomes / total number of outcomes.Calculating the probability of multiple events is a matter of breaking ...
Then, n(S) = Number ways of selecting 3 students out of 25 = 25C3 = 2300. n(E)= (10C1 x 15C2) = 1050. P(E) = n(E)/n(s) = 1050/2300 = 21/46. I know the above method of obtaining answer using formula. But without applying the formula, trying to solve it , gives me a different answer. Probability of selecting girl = 10/25

They divide the sample into groups. For most histograms, the class intervals all have the same width. In Table 1.4, all classes have width 2. The notation 1–<3, 3–<5, and so on, indicates that a point on the boundary will go into the class on its right. For example, a sample value equal to 3 will go into the class 3–<5, not 1–<3.
