[計量] 請教兩題計量
1.Given that there are 30 marbles, in which 6 are red, 7 are pink, 8 are
yellow and remaining are green in color. What are the maximum chances to
select at least two marbles of same color?
被題目混淆
如果看"maximum chances"->只算綠球 因為機率最大?
如果看"at least two marbles of the same color"->全部都加起來?
2.Given two points p(a, b) and q(a^2, b^2) in the coordinate system, where
a < 0 and b > 0.
Col A: The x-intercept of the line passing through the given points
Col B: b
狀況一，當a=-1 b=1，兩點為(-1,1) (1,1)
狀況二，當a=-2 b=2，兩點為(-2,2) (4,4)
所以截距不同，是這樣算嗎
有錯請指正 感謝!!
