an employee is selected from a staff of 10 to super- vise a certain project by selecting a tag at random from a box containing 1

USPshnik [31]

Probability that the number drawn is less than 4 is given by 0.3

<h3>What is probability?</h3>

The likelihood of an event happening is gauged by probability.

The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

The overall chance of every event in a sample space is 1.

Let random variable X represent the number of the drawn tag.

Since the simple space consists of 10 equally likely events

S = {1,2,3,4,5,6,7,8,9,10}

The formula for probability distribution is given by:

f(x) = { (1/10) for x = 1,2....10, else 0 elsewhere

since, each number can equally likely occur, therefore

P(x) = 1/10 = 0.1

Probability that the number drawn is less than 4 is given by:

P(x<4) = P(1) + P(2) + P(3)

= 0.1 + 0.1 + 0.1

= 0.3

4(3x−5)+2x=8????????????

astra-53 [7]

Distribute first. 4 times 3x is 12x and 4 times -5 is -20
12x-20+2x=8 now combine your like terms.
14x-20=8 and add 20 to each side
14x=28 divide
x=2

A lock is using 3 digits from 1 to 7 as its lock combination, the numbers can be repeated. How many different possible lock comb

Oksi-84 [34.3K]

The question is an illustration of selection (or combination)

The number of lock combination is 343

The given parameters are:

<em /> $n = 7$ <em> --- the number of digits to select from</em>

<em /> $r = 3$ <em> --- the number of digits the lock uses</em>

<em />

Because the digits can be repeated, the number of lock combinations is:

$Lock = n^r$

So, we have:

$Lock = 7^3$

$Lock = 343$

Hence, the number of lock combination is 343
