You flip a coin and then roll a 6-sided number cube (a die).
expeople1 [14]

Answer:

a)  No, it does not matter whether you roll the die or flip the coin first, as these two events are <u>independent</u> of each other, which means they do not affect each other.

b) Yes.

  • Let event 1 be flipping a coin and event 2 be rolling a die.
  • Let event 1 be rolling a die and event 2 be flipping a coin.

The likelihood that any outcome will occur will not change, as the events are independent.

c) see attached

d)   12 outcomes  (H = head, T = tail, numbers represent the value of the die)

H 1           T 1

H 2          T 2

H 3          T 3

H 4          T 4

H 5          T 5

H 6          T 6

e)  

\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}

\implies \sf P(even)=\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{6}=\dfrac{3}{6}=\dfrac{1}{2}

\implies \sf P(head)=\dfrac{1}{2}

\implies \sf P(even)\:and\:P(head)=\dfrac{1}{2} \times \dfrac{1}{2}=\dfrac{1}{4}

The question is At the pet fair, there were42 dogs and 35 cats. The pets must be split into small groups so that there are the s
Lelechka [254]
42=2*3*7
35=5*7
their GCF is 7, so the cats and dogs must be split into 7 groups
42/7=6, and 35/7=5, so there are 6 dogs and 5 cats in each group.

Probability and Likelihood
STatiana [176]

The probability that the next elk caught would be unmarked as a fraction is 24/25.

The probability that the next elk caught would be unmarked as a decimal is 0.96.

The probability that the next elk caught would be unmarked as a percentage is 96%.

<h3>What is the probability?</h3>

Probability is used to determine the likelihood that an event would occur.  The chances of the event happening lie between 0 and 1.

The probability that the next elk caught would be unmarked  = total number of unmarked elks / total number of elks

(5625 - 225) / 5625 = 5400 / 5625 = 24/25 = 0.96 = 96%

Here is the rest of the question:

What is the probability of the next elk caught in the park being unmarked? Write the probability as a fraction, a decimal number, and a percentage.
