Suppose a coin tossed then we get … Probability with permutations and combinations. Each card in a standard deck of 52 playing cards is unique and belongs to 1 of 4 suits: Suppose that Luisa randomly draws 4 cards without replacement. What is the probability that Luisa gets 2 diamonds and 2 hearts (in any order)? Now, each of the 36 ordered pairs in the table represent an equally likely outcome. Step 2: To make our analysis easier, let’s replace each ordered pair with the sum (Figure 7.28). Figure 7.28. Step 3: Since the event we’re interested in is the one consisting of rolls of 4, 5, or 7.

Unit 6 Rational exponents and radicals. Unit 7 Exponential models. Unit 8 Similarity. Unit 9 Right triangles & trigonometry. Correct answer: 0.031. Explanation: Probability of each event = (# green marbles + # blue marbles)/ Total # of Marbles. P1 = (15 + 25) / 125 = 40 / 125. Second event assumes a blue or green was chosen for first event so there is one fewer marble on top and also one fewer marble in the total number of marbles.Unit 1 Absolute value & piecewise functions.
