Which event is least likely to occur?

C. picking a 4 of diamonds from a standard deck of cards

Step-by-step explanation:

First, we need to remember what the possible outcomes of a deck of cards, a flipped coin, and a standard number cube are.

A standard deck of cards has a total of 52 cards. There are 4 cards with a 7 on them. There is only one card with a 4 of diamonds. A nickel has 2 sides, and each side is equally likely show after a coin toss. A number cube has 6 faces with a different number from 1 to 6 on each face.

Now we find the probability of each situation. To find the probability of an event, divide the number of ways the desired event can happen by the total number of outcomes.

1. p(7) = 4/52 = 1/13 = 0.0769

2. p(tails) = 1/2 = 0.5

3. p(4 of diamonds) = 1/52 = 0.0192

4. p(number greater than 2) = 4/6 = 2/3 = 0.667

picking a 4 of diamonds from a standard deck of cards

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
