In a scientific experiment, the probability of success on the first trial is 0.3. If the first trial fails, the probability of success on the second trial is 0.4. What is the probability of success on the second trial given that the first trial fails? A. 0.3 B. 0.4 C. 0.7 D. 0.12...
In a binomial experiment with 45 trials, the probability of more than 25 successes can be approximated by$$ P ( z > \frac { 2 5 - 2 7 } { 3 . 2 9 } ) $$. What is the probability of success of a sinale trial of this experiment?Let represent tne numper or successes in su...
A probability experiment is conducted in which the sample space of the experiment isS={3,4,5,6,7,8,9,,11,12,13,14},eventF={7,8,9,10,11},and eventG={11,12,13,14}.Assume that each outcome is equally likely. List the outc...
In a probability experiment, G and H are independent events. The probability that G will occur is r, and the probability that H will occur is s, where both r and s are greater than 0. Quantity A:the probability that either G will occur or H will occur,but not both Quantity B:r+s...
a shuffled deck of cards, etc. have some favourable outcomes (the desired result for experimenter) as compared to a total number of outcomes (every possible result that the experiment can show). The ratio of favourable outcomes to the total number of outcomes gives us th...
Probability of an event is calculated by the number of ways an event can occur divided by the total number of possible outcomes. This definition is called as classical definition of probability.Answer and Explanation: When a pair of six sided dice is rolled the ...
