If a spinner was spun 50 times and the probability to show the number 2 was 0.2, how many times would it show the number 2?

Start by using the probability equation,the probability of an event = the number of ways the event can occur/the total number of possible outcomesFrom the question we know that;the probability of showing a 2 = 0.2we are rolling the dice 50 timesIn this case, the probability of the event is 0.2, the event being landing on the 2.The 50 spins is the total number of possible outcomes and therefore we need to find the number of ways the event can occur.By rearranging the equation:the number of ways the event can occur = the probability of the event x the total number of possible outcomesSo,the number of ways the event can occur = 50 x 0.2 = 10We can check the answer by plugging the 10 into the original equation to solve for the probability of an event.the probability of an event = the number of ways the event can occur/the total number of possible outcomesthe probability of an event = 10/50 = 0.2Thereby, the answer is correct.
