當(dāng)A,C顏色相同時(shí),先染P有4種方法,再染A,C有3種方法,然后染B有2種方法,最后染D也有2種方法.根據(jù)分步乘法計(jì)數(shù)原理知,共有4×3×2×2=48(種)方法;當(dāng)A,C顏色不相同時(shí),先染P有4種方法,再染A有3種方法,然后染C有2種方法,最后染B,D都有1種方法.根據(jù)分步乘法計(jì)數(shù)原理知,共有4×3×2×1×1=24(種)方法.綜上,共有48+24=72(種)方法.故選B.答案:B5.某藝術(shù)小組有9人,每人至少會(huì)鋼琴和小號(hào)中的一種樂(lè)器,其中7人會(huì)鋼琴,3人會(huì)小號(hào),從中選出會(huì)鋼琴與會(huì)小號(hào)的各1人,有多少種不同的選法?解:由題意可知,在藝術(shù)小組9人中,有且僅有1人既會(huì)鋼琴又會(huì)小號(hào)(把該人記為甲),只會(huì)鋼琴的有6人,只會(huì)小號(hào)的有2人.把從中選出會(huì)鋼琴與會(huì)小號(hào)各1人的方法分為兩類(lèi).第1類(lèi),甲入選,另1人只需從其他8人中任選1人,故這類(lèi)選法共8種;第2類(lèi),甲不入選,則會(huì)鋼琴的只能從6個(gè)只會(huì)鋼琴的人中選出,有6種不同的選法,會(huì)小號(hào)的也只能從只會(huì)小號(hào)的2人中選出,有2種不同的選法,所以這類(lèi)選法共有6×2=12(種).因此共有8+12=20(種)不同的選法.
