seven is 0dd only even number can be divided by two like 2,4,6,8,10,10 and so on odd numbers are 1,3,5,7,9,11,13 and so on
In 100 yrs there are 5 odd days..... out of 100 yrs totally 24 leap yrs.: no other century is not leap yr 100 yrs= 24 leap yrs * 76 ord yrs 1 leap yrs= 2 0dd days ord yrs= 1 0dd days 100= 24*2+ 76 =124/7 =5 odd days
You want: P(even) * P(even) * P(even) * P(even). P(even) = 3/6 or 1/2. Therefore probability even on 4 rolls is: 1/2 * 1/2 * 1/2 * 1/2 = 1/16 = 0.0625.
When a die is cast half the possible numbers are even. Therefore the probability is:Probability that die 1 is even = 1/2Probability that die 2 is even = 1/2Probability that both are even = 1/2 * 1/2 = 1/4.
1 in 4. Your choices are to have an odd or even total, which is a 1 in 2 chance. In order to get an even number, you have to have both die even or odd. So that cuts the 1 in 2 in half, giving you a 1 in 4 chance of both dice being even. (1 in 2 for even times 1 in 2 both even gives you 1 in 4.)
