Answer:
There are three kind of beta-thalassemia.
Total possible outcome= 3 types of beta- thalassemia + 1 [child will have no trace of disease] = 4
As we know Probability(outcome) = 
Probability that the child will have beta-thalassemia major =\frac{_{1}^{3}\textrm{C}}{_{1}^{4}\textrm{C}}
=
∴ favorable=
And , Total =
Probability that the child will have no trace of the disease=
Answer:
52 green, 15 orange-Please mark brainliest hope this helped!
Step-by-step explanation:
g + o = 67 g = green, o = orange, x = total
g = 3o + 7
use substitution: (3o + 7) + o = 67
solve for o:
4o + 7 = 67
4o = 60
o = 60/4 = 15
solve for g:
g + 15 = 67
g = 52
Here we are given how much work is done in a fix time interval
then they ask to find the rate of doing the work .
in such problem we can find the rate of doing a work by using the formula :
amount of work done
--------------------------------------------------- = work done in unit time
Time taken to do that amount of work
