There are 5 red shoes, 4 green shoes. If one draw randomly a shoe what is the probability of getting a red shoe
Read Solution (Total 6)
-
- 1 Shoe can be drwan our of 9 shoe = 9C1
1 red shoe can be drwan out of 5 red shoe = 5C1
so, prob = 5C1/9C1 - 13 years agoHelpfull: Yes(4) No(0)
- probablity of getting a red shoe is 5c1/9c1=5/9
- 13 years agoHelpfull: Yes(1) No(2)
- probability for selecting red shoe is
(5c1)/(9c1)
- 13 years agoHelpfull: Yes(1) No(1)
- ans=5/9
1 red shoe out of any 5 red shoe from total 9 shoe - 9 years agoHelpfull: Yes(0) No(0)
- total 9 from take one.
9c1=9
red 5 from one
5c1=5
5/9
ans:5/9 - 9 years agoHelpfull: Yes(0) No(0)
- total no of options= 9 no. of red shoes =5 probablity =5/9
- 6 years agoHelpfull: Yes(0) No(0)
