Answer: 0.3077
Explanation: In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).
Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 7.
With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).
Our denominator here is 52 - the number of cards from which we can pull 1.
Our numerator is both all the diamonds, 13 cards, and all the sevens, 4 cards, but we need to subtract 1 to account for the double counting of the 7 of diamonds.
In all we get: 13+4−1/52=16/52=4/13≈0.3077
Hope this helps... Stay safe and have a great day/night!!!
Answer:
Cream = 3 cups
Chocolate = 6 cups
Step-by-step explanation:
Cream = 1 cup
Chocolate = 2 cups
Total = 3 cups
Cream : chocolate = 1 : 2
He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?
Cream = ratio of cream/total ratio of total cups
= 1/3 of 9
= 1/3 × 9
= 3 cups
Cream = 3 cups
Chocolate = ratio of chocolate/total ratio of total cups
= 2/3 of 9
= 2/3 × 9
= 6 cups
Chocolate = 6 cups

Mason:
time = t
V = 6 ft/s
Distance = v * t = 6t
Nora:
time = t - 60 [ I passed 1 minute to seconds]
V = 8 ft/s
Dsitance = v*t = 8 (t - 60)
Both distance are equal
6t = 8(t-60)
6t = 8t - 480
8t -6t = 480
2t = 480
t = 480/2
t = 240 s
Mason had been swimming for 240 seconds when both had swan the same distance.
