Final answer:
The probability of rolling either a 2 or a 5 on a single six-sided die is 33.3%, which is answer option d. The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes
Step-by-step explanation:
To find the probability of rolling a 2 or 5 with a single six-sided die, you can calculate each outcome's probability and then add them together. There is a 1 in 6 chance of rolling a 2 and the same 1 in 6 chance for rolling a 5. Since these are mutually exclusive events, you add these probabilities to get the total probability of rolling either a 2 or a 5.
The calculation would be 1/6 + 1/6 = 2/6, which simplifies to 1/3. To express this as a percent, you multiply by 100, giving you 33.3%. Therefore, the answer is 33.3%, which corresponds to option d.
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.
The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.
