Autistic children are often evaluated and given a developmental score from 1 to 5, where 1 represents the absence of signs (normal development), and 5 represents the maximal severity of signs (severe retardation). One proposed distribution for the developmental scores of autistic children is as follows:

Developmental Score (X)	P(x)
1	0.13
2	0.13
3	0.17
4	0.47
5	0.1
Total	1.00

Assuming that this probability distribution is correct, answer the following questions (2 decimal accuracy):

The probability that an autistic child has a developmental score of 3 is The probability that an autistic child has a developmental score of at least 3 is
