Probability

What is experimental probability?

• Experimental probability is the probability based on intuition rather than data.

• Experimental probability is the probability obtained from conducting an experiment and observing the outcomes.

• Experimental probability is the probability that never changes.

• Experimental probability is the probability calculated using theoretical formulas only.

How is experimental probability calculated?

• Experimental probability = Number of favorable outcomes * Total number of outcomes

• Experimental probability = Total number of outcomes / Number of favorable outcomes

• Experimental probability = Number of favorable outcomes - Total number of outcomes

• Experimental probability = Number of favorable outcomes / Total number of outcomes

Define probability of simple events.

• The probability of simple events is the sum of all possible outcomes

• The probability of simple events is the likelihood of a single event occurring.

• The probability of simple events is only applicable to complex events

• The probability of simple events is always 1

What is the formula to calculate probability of simple events?

• Probability = Number of favorable outcomes x Total number of possible outcomes

• Probability = Number of favorable outcomes - Total number of possible outcomes

• Probability = Total number of possible outcomes / Number of favorable outcomes

• Probability = Number of favorable outcomes / Total number of possible outcomes
