Explanation:

The number of exhaustive outcomes is 36.

Let E be the event of getting an even number on one die and an odd number on the other. Let the event of getting either both even or both odd then = 18/36 = 1/2

A) 100 π | B) 101/π |

C) 99 π/12 | D) 54/13π |

Explanation:

4/3 π x 10 x 10 x 10 = 8 x 4/3 π rxrxr

r = 5

4π x 5 x 5 = 100π

A) 6 | B) 8 |

C) 4 | D) 5 |

Explanation:

Let the number of boys in the group originally be x.

Total weight of the boys = 30x

After the boy weighing 35 kg joins the group, total weight of boys = 30x + 35

So 30x + 35 + 31(x + 1) = > x = 4.
