![\bold{P(x)=\ ^nC_xp^x(1-p)^{(n-x)}} \\ \\ \bold{P(0)}=\ ^5C_0(0.4)^0(1-0.4)^{(5-0)} \\ \\ =1\times1\times(0.6)^5=0.07776 \\ \\ \bold{P(1)}=\ ^5C_1(0.4)^1(1-0.4)^{(5-1)} \\ \\ =5\times0.4\times(0.6)^4=2\times0.1296 \\ \\ =0.2592 \\ \\ \bold{P(0)+P(1)}=0.07776 + 0.2592=0.33696 \\ \\ \bold{\therefore P(2\ or\ more\ offers)}=1-[P(0)+P(1)] \\ \\ =1-0.33696=0.66304](/tpl/images/0045/5361/b21e9.png)
