If the odds against a student receiving an A grade in a mathematics class are 7 to 3, what is the probability that a student in a mathematics class will receive an A grade?

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
