Independent events, so P(both)=(5/26)(4/10)=0.07692307692. The 4/10 comes from the fact that 0, 3, 6, and 9 are the 4 digits that are multiples of 3.
It is 3/52. This assumes that all letters and numbers are used. In fact, some letters are not used because they resemble numbers and may lead to confusion.
There was a demand for a huge number of manual calculations to create tables - many of them for navigational purposes - where similar calculations needed to be repeated many times.
Calculus is interesting because it is incredible that human intelligence has discovered a way to solve a problem using a formula that can be repeated. Calculus is not necessarily about the numbers, but about the fact that we can apply rules and theories to numbers in a variety of situations.
This is one minus the probability of having no repeated letters. The probability of having no repeated numbers is 10/10 x 9/10 x 8/10 x 7/10 x 6/10 x 5/10 which equals 0.1512. The probability of having no repeated letters is 26/26 x 25/26 = 0.96153846153846153846153846153846 These multiplied together gives 0.14538461538461538461538461538462 1 minus this is 0.85461538461538461538461538461538 And so the probability of having a repeater letter or digit is roughly 0.855
Experimental Probability
It is empirical (or experimental) probability.
The number of license plates without a repeated letter or digit is 26x25x24x10x9 = 1 404 000. The number of license plates without any restriction is 26x26x26x10x10 = 1 757 600. Probability of a license plate without a repeated letter or digit = 1 404 000 /1 757 600 = 0.7988 Probability of a license plate with a repeated letter or digit = 1-0.7988 = 0.2022
It is the probability of an event calculated from repeated trials of an experiment.
Because it is the process of deriving probability through repeated experiments.
The experimental probability of an event is the probability that is calculated from repeated trials rather than from theoretical models.
The probability that is based on repeated trials of an experiment is called empirical or experimental probability. It is calculated by dividing the number of favorable outcomes by the total number of trials conducted. As more trials are performed, the empirical probability tends to converge to the theoretical probability.
infinite
It is possible to create a 3-digit number, without repeated digits so the probability is 1.
when a probability experiment is repeated a large number of times, the relative frequency probability of an outcome will approach its theoretical probability.
because they use the effect on probability.
