Answer:

The probability of tails coming up is \dfrac{3}{5}

D is correct

Step-by-step explanation:

Suppose a coin has been altered so that the probability of heads coming up is 2/5.

A coin has two possibility either head or coin.

We are given probability of heads coming up is 2/5

P(H)=\dfrac{2}{5}

The sum of probability of all value is 1.

P(H)+P(T)=1

\dfrac{2}{5}+P(T)=1

                   P(T)=1-\dfrac{2}{5}

                   P(T)=\dfrac{3}{5}

Hence, The probability of tails coming up is \dfrac{3}{5}

It is recommended that you use 3.75 pound of fertilizer to cover 1,200 square feet. How much space can you cover with a 1-pound
uysha [10]

Answer:

320 square feet

Step-by-step explanation:

To find the space you can cover with 1-pound bag of fertilizer, we need to divide 1,200 by 3.75. It makes things easier to think of how 3.75 ÷ 3.75 = 1. Anyways, 1,200 ÷ 3.75 = 320. Therefore, you can cover 320 square feet with a 1-pound bag of fertilizer.

(a) suppose 3 children in a village ages 3, 5, and 7 are vaccinated with the qiv vaccine. what is the probability that at least
murzikaleks [220]

The probability that at least one child among the 3 will get influenza is 0.07.

<h3>Define probability.</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given,

3 children in a village ages 3, 5, and 7 are vaccinated with the qiv vaccine

Probability that at least one child among the 3 will get influenza

P(at least one child among the 3 will get influenza)

=  1 - P(no one have influenza)

= 1 - (1- 0.0.378)(1-0.017)²

= 1 - 0.93

= 0.07

The probability that at least one child among the 3 will get influenza is 0.07.
