The probability that a plant in the experiment receives visible or ultraviolet light is 7/10.
<u>Step-by-step explanation</u>:
The total number of plants in the experiment = 30 plants
Plants that receive visible light alone = 12 plants
Plants that receive ultraviolet light alone = 15 plants
Plants that receive both visible and ultraviolet light = 6 plants
<u>step 1</u> :
<em>Probability = No. of required events / Total number</em>
<u>step 2</u> :
P(visible) = 12 / 30
P(ultraviolet) = 15 / 30
P(both) = 6 / 30
<u>step 3</u> :
P(visible or ultraviolet) = P(visible) + P(ultraviolet) - P(both)
= 12/30 + 15/30 - 6/30
= 21/30
P(visible or ultraviolet) = 7/10
Answer:
Step-by-step explanation:
1. Draw a line down the middle of the equal sign .
2.Divide 4x/4. Which equals x.
3. Divide 6/4. Which equals 1 and 2/4 or 1 and 1/2.
4. X=1 2/4
5. Check=
Y=4x+6
Plug 4 with 1 2/4. Which equals 6.
6+6=12
X=1 2/4 Y=12
