Answer:
it's 30/45
Step-by-step explanation:
because there are 12 green and 18 red which equal 30. Then there are 45 eggs in total. So 30/45
Probability of selecting a green or red egg is equals to [tex]\frac{30}{45}[/tex].
What is probability?
" Probability is defined as ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability [tex]= \frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Given,
Total number of dyed eggs [tex]= 45[/tex] dyed eggs
Number of yellow eggs [tex]= 15[/tex]
Number of green eggs [tex]= 12[/tex]
Number of red eggs [tex]= 18[/tex]
Substitute the value in the formula to get the probability of each required colour egg,
Probability of green egg [tex]P(G)= \frac{12}{45}[/tex]
Probability of red egg [tex]P(R)= \frac{18}{45}[/tex]
Both are independent therefore,
P( G ∩ R) [tex]=0[/tex]
Probability of selecting a green or red egg [tex]= P(G) + P(R)[/tex]
[tex]= \frac{12}{45} + \frac{18}{45}\\\\= \frac{30}{45}[/tex]
Hence, probability of selecting a green or red egg is equals to [tex]\frac{30}{45}[/tex].
