Andrew [12]

Answer:

Step-by-step explanation:

Given that a box contains 45 light bulbs, of which 36 are good and the other 9 are defective.

Probability for any one to be defective as of now is \frac{36}{45} =0.80

a) P(E) = 0.80

b) After I draw we have 35 good ones and 9 defective

P(F/E) =\frac{35}{44} \\=0.796

c) P(G/EF)

This is the probability for iii bulb to be good given I and II are goog.

Once I and ii are good we have 43 bulbs with 34 good ones

P(G/EF) =\frac{34}{43} \\=0.7907

Which equation shows the inverse property of multiplication?
serious [3.7K]

Answer:

C

Step-by-step explanation:

The options are:

<em>A. 4 + (-4) = 0 </em>

<em>B. -8 + (-3) = -3 + (-8) </em>

<em>C. 2 </em>×<em> 1/2 = 1 </em>

<em>D. 8/5 + 0 = 8/5</em>

<em />

The inverse property of multiplication states that the product of a number and its inverse is one.

The inverse of 2 is 1/2. The multiplication of 2 × 1/2 = 1 , as the property states.
