The ratio of successful events A = 4 to the total number of possible combinations of a sample space S = 8 is the probability of 2 heads in 3 coin tosses. Users may refer the below solved example work with steps to learn how to find what is the probability of getting at-least 2 heads, if a coin is tossed three times or 3 coins tossed together. Because there are 4 parts to the spinner and 2 of them are red, we have a 2 out of 4 chance to spin red. The probability is 2 out of 4. Of the 4 parts, 1 is blue. What are the chances the spinner will land on blue? Type your answer in the blank.
